Using the image I gave you, you don't need to solve for x.
So tan is opposite/adjacent
sin: opposite/hypotenuse
cos: adjacent/hypotenuse
Take theta and do: adjacent/hypotenuse which is cosine
cos theta = adjacent/hypotenuse
cos theta = 1.5/9
inverse cos = 1.5/9 and the answer is: 80.4 degrees
Answer: Hello there!!! the answer is - 91
Step-by-step explanation:
Step 1: convert all of the variables in the equation into numbers.
The equation will look like this - 8^2 + 3^3
Step 2: solve 8^2 and 3^3
8^2 = 64 and 3^3 = 27
Step 3: solve the equation sooooo the equation will now look like this
64 + 27 which is 91
PLEASE MARK ME BRAINLIEST I WOULD HIGHLY APPRECIATE IT!!!!!!
Answer:
162 m²
Step-by-step explanation:
To find the area of this composite solid, we need to find the area of each surface and sum them up.
Formula for finding area is length x width.
Area of each surface:
3 * 2 = 6
9 * 2 = 18
5 * 2 = 10
2 * 2 = 4
8 * 2 = 16
(11-2) * 3 = 27
Considering the fact that each surface appeared twice in the figure, the area of the surface will be calculated as:
(6 + 18 + 10 + 4 + 16 + 27) * 2
= 81 * 2
= 162 m²
