Answer:

Step-by-step explanation:
<u>Right Triangles</u>
The ratios of the sides of a right triangle are called trigonometric ratios. Each acute angle has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
The tangent ratio is defined as:

The opposite side is 25 and the adjacent side is 18, thus:

The angle is calculated by using the inverse tangent function:


Y = mx + b
m = slope of the line
b= y-intercept
Since you are given the point (4,1/3), the y-value is 1/3.
So plug in the numbers and solve for b:
(1/3)= (3/4)*(4) + b
After you solve the equation for b, you should get -2 2/3 or -8/3
No rewrite the equation with the y-intercept, b.
y = (3/4 x) - (8/3)
A. Proper
B. Improper
C. Improper
D. Proper
(a) is the first one. 48 I would say 8 mins
(b) is the second one. 10 I would say is 96
