Lets try 96
4 x ?= 96
? = 96/4
= 24
So we see that 4 times 24 is close to 97.
A right angle is an angle with a measure of 90 degrees.
Answer:
84.5
Step-by-step explanation:
Use trig functions to find x. Trig functions are special relationships which exits between the sides of right triangles. Since you need to find x the hypotenuse and you have the adjacent side to 77 degree angle use cosine.
Cos 77 = 19/x
0.22495 = 19/x
19/0.22495 = x
84.5 = x
