Answer:
MQ=14
Step-by-step explanation:
The two triangles are similar
So the equation is
12/72=x/12
1/6=x/12
x=2
The expression would be (5*6)+(5*6)=x
or you could shorten it and do (10*6)=x
Answer:
∠ YZX ≈ 19.7°
Step-by-step explanation:
using the sine ratio in the right triangle.
sin YZX = 
= 
= 
, then
∠ YZX = 
( ) ≈ 19.7° ( to 3 significant figures )
189 inches is 15.75 feet
16 ft - 15.75 ft = 0.25 ft
0.25ft = 3 inches
He must vault 3 inches higher
