Step 1: Set Up Equation

69° + 62° + (x + 54)° = 180°

Step 2: Solve for x

Answer:

Step-by-step explanation:

x + 54 + 69 + 62 = 180         Every triangle has 180 degrees

x + 185 = 180                        Subtract 185 from both sides

x = - 5

Answer:

Figure B

Step-by-step explanation:

Figure B has three triangles, and 2 triangles make 1 square. So there are 1 1/2 squares :)

Answer:

The value of [tex]f = x_{1}+10\cdot y_{1}+x_{2}+10\cdot y_{2}[/tex] is 317.

Step-by-step explanation:

Let the system of nonlinear equations be:

[tex]x\cdot (y-1) = 180[/tex] (1)

[tex]y\cdot (1+x) = 208[/tex] (2)

From (1), we clear [tex]x[/tex]:

[tex]x = \frac{180}{y-1}[/tex]

Let apply this resulting expression in (2):

[tex]y\cdot \left(1+\frac{180}{y-1} \right)= 208[/tex]

[tex]y\cdot \left(\frac{y-1+180}{y-1} \right) = 208[/tex]

[tex]y\cdot \left(\frac{y+179}{y-1} \right)=208[/tex]  

[tex]y\cdot (y+179) = 208\cdot (y-1)[/tex]

[tex]y^{2}+179\cdot y = 208\cdot y-208[/tex]

[tex]y^{2}-29\cdot y+208 = 0[/tex]

By the Quadratic Formula we obtain the solution of the second order polynomial:

[tex]y_{1} = 16[/tex] and [tex]y_{2} = 13[/tex]

And the respective values of [tex]x[/tex] are, respectively:

[tex]y_{1} = 16[/tex]

[tex]x_{1} = \frac{180}{y_{1}-1}[/tex]

[tex]x_{1} = \frac{180}{15}[/tex]

[tex]x_{1} = 12[/tex]

[tex]y_{2} = 13[/tex]

[tex]x_{2} = \frac{180}{y_{2}-1}[/tex]

[tex]x_{2} = \frac{180}{12}[/tex]

[tex]x_{2} = 15[/tex]

If we know that [tex]x_{1} = 12[/tex], [tex]y_{1} = 16[/tex], [tex]x_{2} = 15[/tex] and [tex]y_{2} = 13[/tex], then the value of [tex]f = x_{1}+10\cdot y_{1}+x_{2}+10\cdot y_{2}[/tex] is:

[tex]f = 12+10\cdot (16)+15+10\cdot (13)[/tex]

[tex]f = 317[/tex]

The value of [tex]f = x_{1}+10\cdot y_{1}+x_{2}+10\cdot y_{2}[/tex] is 317.

Answer: 14

Step-by-step explanation:

3 1/2÷1/4=

3 1/2*4=       ==> dividing by fractions is basically multiplying by the reciprocals of the fraction

(3+1/2)*4=

3*4+1/2 * 4=

12+2=14

Answer:

3 1/2÷1/4 = 14

Step-by-step explanation:

Divide 3 x 2 + 1 / 1 by 1 / 4 by multiplying 3 x 2 + 1 / 1 by the reciprocal of 1/4

Multiply 3 and 2 to get 6

Add 6 and 1 to get 7

Multiply 7 and 4 to get 28

Divide 28 by 2 to get 14

answer = 14

Step-by-step explanation:

Answer:

6.517%

Step-by-step explanation:

This is a multi-year investment and we are not working with a $1 initial investment. There is no mention of compounding so we will use formula A=P0⋅(1+r)N with A=$18,434 and P0=$14,320. We do not know the value of r. However, N=4 years. Substituting the values we have $18,434=$14,320⋅(1+r)4. Divide both sides of the equation by $14,320. Next, take the fourth root of both sides of the equation and subtract 1 to find the decimal form of r.

$18,4341.287291.065170.06517=$14,320⋅(1+r)4=(1+r)4=1+r=r

Finally, convert r to a percent.

r=0.06517×100%=6.517%

Answer:

Step-by-step explanation:

Answer:

y = -7/8x - 97/8

or 8y + 7x = -97

Step-by-step explanation:

7x + 8y = 18

=> 8y = -7x + 18

y = -7/8 + 18/8

If two lines are parallel, their slopes are equal. So slope is -7/8

given m = -7/8, y = -13, x = 1

y = mx + b

-13 = -7/8(1) + b

-13 = -7/8 + b

b = -13 + 7/8 = -104/8 + 7/8 = -97/8

so y = -7/8x - 97/8

=> 8y = -7x - 97

8y + 7x = -97

Answer:

[tex] \fbox{A triangle can have 2 acute angles.}[/tex]

Step-by-step explanation:

Acute angle : The angle whose measure is less than 90° is called actute angle.

Obtuse angle : The angle whose measure is more than 90° is called obtuse angle.

Right angle : The angle whose measure is exact 90° is called right angle.

Property of triangle: The measure of all three angles of a triangle is 180°.

let's solve the actual question now,

Option A - let a triangle have two acute angle x and y respectively and z third angle of the respective triangle,

x + y + z = 180°

(<90°) + (<90°) + z = 180°

z = 180 - (<180)

z <180

the measure of 3rd angle z will be less than 180,

hence a triangle can have 2 acute angles.

Option B - let a right angle triangle have two right angles x and y respectively and z third angle of the respective triangle,

x+y+z = 180

90+90+z = 180

z = 180-180 = 0°

which means the third angle z does not exist and it is not a triangle. Hence a right angle triangle can only have one right angle.

Option C - let a triangle have two obtuse angle x and y respectively and z third angle of the respective triangle,

x + y + z = 180°

(>90°) + (>90°) + z = 180°

z = 180 - (>180)

when one number is subtracted from another number which is greater than that then the result obtain is negative. So the value of third angle z will be negative which is a flaw. Hence third option is also incorrect.

Option D - let a triangle have one right angle and one obtuse angle x and y respectively and z third angle of the respective triangle,

x + y + z = 180°

(90°) + (>90°) + z = 180°

z = 180 - (>180)

Same as option C, the third angle is negative which is a flaw and this option is incorrect too.

Conclusion- A triangle can have 2 acute angles and one right angle. So option A is the correct match.
