Answer:

Part 1) x=28.75\°

Part 2) z=44.5\°

Part 3) y=135.5\°

Step-by-step explanation:

Part 1) Determine the value of x

we know that

(\frac{6}{5}x+10)\°=(2x-13)\° ------> by corresponding angles

Solve for x

Multiply by 5 both sides to remove the fraction

5(\frac{6}{5}x+10)\°=5(2x-13)\°

6x+50=10x-65

10x-6x=50+65

4x=115

Divide by 4 both sides

x=28.75\°

Part 2) Determine the value of z

we know that

z=(\frac{6}{5}x+10)\° ------> by corresponding angles

we have

x=28.75\°

substitute the value of x and solve for z

z=(\frac{6}{5}(28.75)+10)=44.5\°

Part 3) Determine the value of y

we know that

y+z=180\° ------> by supplementary angles

we have

z=44.5\°

substitute and solve for y

y+44.5\°=180\°

y=180\°-44.5\°=135.5\°

f(0)=(1/5)(0)
f(0)=0✓
f(5)=(1/5)(5)^2
f(5)=(1/5)(25)
