# An airplane has leveled off (is flying horizontally) at an altitude of 12, 000 feet. Its pilot can see each of two farmhouses at points R and T in front of the plane. With angle measures as indicated, find m ∠ R To determine

To find:

The value of mR.

Explanation

Given:

The airplane is at an altitude of 12, 000 feet.

Figure (1)

Approach:

The sum of the interior angles on the same side of the transversal which cut by two parallel lines is equal to 180°.

Calculation:

R and 65° are two angles on the same side of the transversal as shown in figure (1).
