Answer:
Length of the ramp = 18.6 feet (Approx.)
Step-by-step explanation:
Given:
Horizontal distance (base distance) = 17 feet
Angle of elevation = 24°
Find:
Length of the ramp
Computation:
Cosθ = Length of base / Length of hypotenuse
Cos 24 = Horizontal distance (base distance) / Length of the ramp
Cos 24 = 17 / Length of the ramp
0.9135 = 17 / Length of the ramp
Length of the ramp = 17 / 0.9135
Length of the ramp = 18.6 feet (Approx.)
The answer is A, 75 degrees
add all like terms
2x+196
all triangles equal 180 degrees
2x+196=180
subtract the 196 from 180
2x= -16
divide
x= -8
plug into angle A
-8+83
A=75
Answer:
41,6 cm
Step-by-step explanation:
Formula for Perimeter of a rhombus: P = 2L + 2H (H is the height, L the length)
Perimeter: 160 cm = 2L + 2(38,4 cm), or
160 cm + 76.8 cm + 2L, or
83.2 cm = 2L
and so the height (altezza) is H = 83.2 cm / 2 = 41,6 cm
Radius is normally used for a circle
in a circle, radius is the distance form the center of the circle to the outer edge of the circle
area=legnth times width or in square area=legnth times legneth
since this is a square and this is a math problem, we will assume that radius=1/2legnth so
if radius=16 then legnth =2 times 16=32
area=32 times 32=1042
area=1042 square cm or 1042 cm^2
