Use the triangle Sum t h e o r e m to find the measure of the angles for the triangle in the diagram B five times plus four eight four times plus 14 c 6 * - 3A 57° 54° and 69° B 59° 58° and 63° c 54°, 44 degrees and 82 degrees d 59°, 63° and 48°

To use the Triangle Sum Theorem, we add up the measures of all three angles in the triangle and set it equal to 180 degrees.

Let's calculate it for the given angles:

B = 5(48) + 4 = 244 degrees
C = 4(84) + 14 = 350 degrees
A = 6 × (-3) = -18 degrees

Now we can add up all three angles:

A + B + C = -18 + 244 + 350 = 576 degrees

Since this doesn't equal 180 degrees, the given angles do not form a valid triangle.
