You would take the 38 and place over 100 since its in percent (part over whole) and then you'd place the n over 90 (part you are looking for over whole)
so.....the 3rd one is correct
Complementary angles sum to 90°. Supplementary angles sum to 180°.
Answer:
Down below
Step-by-step explanation:
51+1 if you add them it equals
10 times 5 plus 2
104 divided by 2
You’re going to want to use the pythagorean theorem (a^2+b^2=c^2). Start with what you know your hypotenuse is 53 ft (c) and one of your sides is 45 ft (a). Plug in the equation: (45^2+b^2=53^2). Next square each side: (2025+b^2=2809). Then: (b^2=784). Finally square root: (b=28) So your answer is x=28 ft.
Answer:
B. 36 square units
Step-by-step explanation:
This is a triangle and to calculate the area of a triangle we multiply height with base and that divided by two
The height of this triangle is 8 units and the base is 9 units
9 × 8 ÷ 2 = 36 square units
