4 + x² = 25
21 = x²
x = 4.58258

Multiply it all together 3/4 is 0.75 2/3 is 0.66 1/2 is 0.5 now do in your calculator 0.75+0.66+0.5 and becase everything is in fractions remember that you have to convert your decimal into a fraction your answer is 1 91/100
Width of the rectangle is 14 ft
Step-by-step explanation:
- Step 1: Let the width of the rectangle be x. Then length = 8 + x. Perimeter = 72 ft.
Perimeter = 2(length + width)
72 = 2 (8 + x + x)
72 = 16 + 4x
4x = 56
x = 56/4 = 14
∴ Width of the rectangle is 14 ft
Answer: Sine - Sin
Tangent - Tan - Cosine - Cos
or inverse Cos-1 - Sin-1 - Tan-1
Step-by-step explanation:
You would use Sine - Sin for Opposite over hypotenuse
to check it you'd use Sin-1 that is just Sine but inverse that helps you get the answer- I just learned this stuff so bare with me but all of it is the same
I'm hoping I helped give you a small clue
