Answer:
Step-by-step explanation:
We have two congruent right triangles and three rectangles.
First, calculate the length of the hypotenuse using the Pythagorean theorem:
We have
Substitute:
The formula of an area of a right triangle:
Substitute:
The formula of an area of a rectangle:
w - width
l - length
Rectangle 1:
w = 15, l = 22
Rectangle 2:
w = 17, l = 22
Rectangle 3:
w = 8, l = 22
The Surface Area of the triangular prism:
Substitute:
Answer:
The missing angle 'x' is 22.29°.
i.e.
Step-by-step explanation:
Let 'x' be the missing angle of the triangle.
Using the formula
tan x = opp ÷ adjacent
tan x = 30 ÷ 72
tan x = 0.41
Therefore, the missing angle 'x' is 22.29°.
i.e.
