Answer:
1. 28
2. b = 7.06
2. c = 3.76
Step-by-step explanation:
1. m < C = 90 - B = 90 - 62 = 28 degrees
2. sin B = opposite/hypotenuse
sin (62o) = b/8
b = 8 x sin (62o) = 8 x 0.883 = 7.06
3. sin C = opposite/hypotenuse
sin (28o) = c/8
c = 8 x sin (28o) = 8 x 0.4695 = 3.76
Answer: Root 7 would equal 2.64575131106 and would go on forever.
Step-by-step explanation: It isn't one of the perfect squares. For example, the first 10 perfect square are 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
Answer: x=-20
Explanation: Multiply both sides by 10
7x = -140
Divide both sides by 7
7x/7 = -140/7
x=-20
Answer:
1.4°
Step-by-step explanation:
Given that :
Height of ramp, h = 5 feets
Horizontal distance = 200 feets
The angle of elevation :
Using trigonometry :
Tanθ = opposite / Adjacent
Tan θ = 5 / 200
Tan θ = 0.025
θ = tan^-1 (0.025) = 1.43
θ = 1.4°
