Answer:
Step-by-step explanation:
The sum of angles in a triangle is 180°, so angle x is the complement of the one marked 31°.
x = 90 -31
x = 59
__
The tangent relation tells you ...
tan(31°) = 10/y
y = 10/tan(31°) = 10/0.6009
y ≈ 16.64
The sine relation tells you ...
sin(31°) = 10/z
z = 10/sin(31°) = 10/0.5150
z ≈ 19.42
x = 5
2 = x-3
<em>Adding 3 to both sides</em>
2+3 = x
5 = x
<u><em>OR </em></u>
the answer is 2x²-6x-36
48
x/3 - 6 = 10
+6 +6
x/3=16
16*3=48
h=240-97
