Answer:
D y= 81
Step-by-step explanation:
Since the triangles are similar, the ratios of similar sides must be equal.
30/54 = 45/ y
We can use cross products
45*54 = 30*y
2430=30y
Divide each side by 30
2430/30 = 30y/30
81 =y
Answer:
x = 60.5°
Step-by-step explanation:
We use the exterior angle theorem to solve this
90 + 31 = 121
121/2 = 60.5
Thus, our answer is 60.5°
