The angles inside a triangle are called interior angles. The diagram below shows the interior and exterior angles of a triangle. The three interior angles in a triangle will always add up to 180°. At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°.
Answer:
Step-by-step explanation:
[(4 + 2) - 1] x 3
[6 - 1] x 3
5 x 3
15
-15 degrees = -15 pi / 180 = -pi/12 radians
convert 7pi/6 to degrees
= 7pi/6 * 180 /pi = 210 degrees which is in Quadrant III
Step-by-step explanation:
In my opinion Option A is the correct answer because
Product of 3 and x = 3x
7.5 more than that = 3x + 7.5
