What do u mean by missing measurement?
m∠B = 31.7° , a = 21.1 ft , b = 13.0 ft
Step-by-step explanation:
If ABC is a right triangle, where the right angle is B, then
- The hypotenuse of the triangle is b and a , c are its legs
- sin(A) =

- sin(C) =


- The sum of the measures of the two acute angles A and C is 90°
∵ ABC is a right triangle
∵ m∠C = 90°
∴ c is the hypotenuse and a , b are its legs
∵ m∠A = 58.3°
- The sum of the two acute angles in the right triangle = 90°
∴ m∠A + m∠B = 90°
- Substitute the measure of angle A
∴ 58.3 + m∠B = 90
- Subtract 58.3 from both sides
∴ m∠B = 31.7°
∵ sin(A) = 
∵ c = 24.8 feet
∴ sin(58.3) = 
- By using cross multiplication
∴ a = (24.8) × sin(58.3)
∴ a = 21.1 ft
∵ sin(B) = 
∵ c = 24.8 feet
∴ sin(31.7) = 
- By using cross multiplication
∴ b = (24.8) × sin(31.7)
∴ b = 13.0 ft
m∠B = 31.7° , a = 21.1 ft , b = 13.0 ft

Answer:
f(- 5) = 25
Step-by-step explanation:
To evaluate f(- 5) , substitute x = - 5 into f(x) , that is
f(- 5) = - (- 5)² - 10(- 5) = - 25 + 50 = 25
Answer:
A, 8
Step-by-step explanation:
Use the equation 15+4x=47
Subtract 15 from both sides to get
4x=32
divide to get 8
x=8
4 sides idk the area part I'm in middle school I forgotten it lol
