Answer:
2(7) + 5 = 19
Step-by-step explanation:
Okay, so do it like this:
2x+5
x = 7
2(7) + 5
2(7) = 2 x 7
2 x 7 = 14
Now it's 14 + 5
14 + 5 = 19
Your answer is 2(7) + 5 = 19
Hi there!

We can begin by finding ∠VUY so we can solve for ∠UVY.
∠VUY is supplementary to ∠TUY, so:
180 = 144 + ∠VUY
∠VUY = 36°
In a triangle, angles sum up to 180°, so:
180 = 36° + 79° + m∠UVY
m∠UVY = 65°
Solve for m∠VYZ by comparing the angle to m∠UVY because the angles are alternating interior angles. Thus:
m∠UVY = m∠VYZ = 65°.
