B.m∠1 = 35°, m∠2 = 30°
C.m∠1 = 65°, m∠2 = 60°
D.m∠1 = 85°, m∠2 = 80°

Answers

Answer:

B

Step-by-step explanation:

First find the third angle straight linear make 180° so

180°-115°=65°

So 80°+65°+X=180°..triangle measure 180°

145°+X=180

X=180-145

X=35°

The second one. Again straight linear measure 180° so

180°-115°=65°

65°+85°+ Y=180°

150°+ Y=180°

X=180°-150°

Y=30°

+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.

a+b=−4

ab=4

Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 4.

−1,−4

−2,−2

Calculate the sum for each pair.

−1−4=−5

−2−2=−4

The solution is the pair that gives sum −4.

a=−2

b=−2

Rewrite factored expression (x+a)(x+b) using the obtained values.

Solve f(x)= x2 when x = 5.

Answers

Answer:

10

Step-by-step explanation:

Answer:

f = 2

Step-by-step explanation:

f(x) = x2  ...  when 'x' is equal to 5

So...

1.) Plug in 5 for the variable 'x'

f(5) = (5) * (2)

2.) Simplify both sides of the equation

5f = 10

3.) Divide both sides by 5

5f /5  =  10/5

f = 2
