55/100 = (55:5)/(100:5) = 11/20
55/100 = 0.55
Basically, you need to calculate "x" correct?
The tangent of (52) = x / 20
1.2799 = x / 20
x = 1.2799 * 20

Answer:
x = 8.0 m
Step-by-step explanation:
With the angle presented, I'm assuming you know basic trigonometry. We know cosθ = adj/hyp from SOH CAH TOA. We have angle and hypotenuse, so plugging in those values we get cos(20°) = x / 8.5. Solve for x to get 8.5cos(20°) = 7.987387277 m = 8.0 m.
Answer: 3/2
Step-by-step explanation:
The first one: y=2x+5
X=2y+5.Then solve for y after switching x and y
X-5=2y, X-5/2=y
Since F-1= X-5/ 2, we plug the value of X in
8-5/2, so it should be 3/2
Answer:
30, 66 and 84 degrees.
Step-by-step explanation:
The number of degrees in a triangle is 180 degrees.
Work out the 'multiplier':
It = 180 / (14+5+11)
= 180/30
= 6.
So the angles are:
14*6 = 84
5*6 = 30
11*6 = 66.
