Find the value of x and y.
Answer:
x=25, y=19
Step-by-step explanation:
130+2x=180
x=25
54+2x+4y=180
y=19
Answer:
x = 25 , y = 19
Step-by-step explanation:
130° and 2x° are adjacent angles on a straight line and sum to 180° , so
130 + 2x = 180 ( subtract 130 from both sides )
2x = 50 ( divide both sides by 2 )
x = 25
--------------------------------------------------------------
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
130° is an exterior angle of the triangle , then
54 + 4y = 130 ( subtract 54 from both sides )
4y = 76 ( divide both sides by 4 )
y = 19

Choose the correct description of each system of equations.
3x + y = 3
x - 2y = 4
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
Given the system of equation expressed as:
3x + y = 3
x - 2y = 4
Solve simultaneosly;
3x + y = 3 ............. 1 * 1
x - 2y = 4 ...............2 * 3
_________________________
3x + y = 3
3x - 6y = 12
Subtract
y-(6y) = 3 - 12
7y = -9
y = -9/7
Substitute y = -9/7 into the equation to get x
x - 2y = 4
x - 2(-9/7) = 4
x + 18/7 = 4
x = 4 - 18/7
x = 3/7
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Find the missing angle measurement! Please show/tell me what u did to solve the problem aswell
Answer:
x = 12
Step-by-step explanation:
The sum of exterior angles is = 360
one of the angle is given we will need to add all three angles
128 + 8x + 11x + 4 = 360 add like terms
19x + 132 = 360 subtract 132 from both sides
19x = 268 divide both sides by 19
x = 12 replace x in required expressions to find the measure of the angles

Step-by-step explanation:
remember, i = sqrt(-1)
you know what an exponent means, right ?
it means you multiply the enclosed term that many times with itself.
when you envision this as a long chain of (1+i)/(1-i) multiplications, you can see you can group them into pairs, and then multiply these pairs - just half the times than for the single terms.
so,
((1+i)/(1-i))²⁰²⁰ = ((1+i)/(1-i))² ^ 1010
to get an idea what the result of the long chain of multiplications might be, let's start with the square and see, if we can find a pattern, that we then can use to come to a conclusion about the total result.
((1+i)/(1-i))² = (1+i)²/(1-i)²
(1+i)² = 1×1 + 1×i + 1×i + i² = 1 + 2i - 1 = 2i
(1-i)² = 1×1 - 1×i - 1×i + i² = 1 - 2i - 1 = -2i
so,
((1+i)/(1-i))² = 2i/-2i = -1
aha !
so,
((1+i)/(1-i))² ^ 1010 = (-1)¹⁰¹⁰
just to be sure you understand, we use the same trick again
(-1)¹⁰¹⁰ = (-1)² ^ 505 = 1⁵⁰⁵ = 1
as 1 to any power is always 1.
so, the right answer is A.
remember, a negative number to an even power results always in a positive number. and to an uneven/odd power in a negative number.
again, because such an exponent is only the summary of many multiplications.

For each set of three measures, determine if they can be angle measures of a triangle.
Answer:
NO
NO
YES
NO
Step-by-step explanation:
The sum of the angles has to be equal to 180° because the sum of the angles in a triangle is 180°
The first one is already more that 180°, because you are adding 2 angles that are more than 100°
The sum of the second one is equivalent is 160°
The sum of the third one is equivalent to 180°
The sum of the fourth one is more than 180°
