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°.
Answer:
D
Step-by-step explanation:
The problem with D is that 7 + 11 = 18. The rule is any two sides must exceed the third. D gives the shorter + the middle length = the longest length.
That can't work. All the others are fine.
Answer:
Step-by-step explanation:
<u>Given</u>
<u>Simplify</u>
Compare left and right sides and
<u>Find b:</u>
- <u />
b = 15 ⇒ b = 15*3/5 = 9
<u>Find c:</u>
- 1 + c = 7 ⇒ c = 7 - 1 = 6
<u>Find a:</u>
- a + 2 = 10 ⇒ a = 10 - 2 = 8
<u>Find d:</u>
