x=100 degrees
y=50 degrees
size doesn't cange angles
Step-by-step explanation:
Applying the tangent ratio, the distance from A to C across the gorge, is: 60.6 ft.
<h3>What is Tangent Ratio?</h3>
The tangent ratio for solving a right triangle is given as, tan ∅ = opposite/adjacent.
Given the following:
- ∅ = 25°
- Adjacent length = 130 ft
- Opposite length = AC
Apply the tangent ratio:
tan 25 = AC/130
AC = (130)(tan 25)
AC = 60.6 ft

#SPJ1
Y = mx + b....m is the slope and b is the y intercept
slope(m) = 5...(4,0)...x = 4 and y = 0
now we sub our info into y = mx + b...we r looking for b, the y intercept
0 = 5(4) + b
0 = 20 + b
-20 = b
so ur equation is y = 20x - 20...but we need it in standard form
Ax + By = C
y = 20x - 20....subtract 20x from both sides
-20x + y = -20...multiply by -1 to make x positive
20x - y = 20 <== standard form
