IF TRIANGE M<A =63 degrees and m<C=99 degrees what is the measure of angle B
The sum of the interior angles in a triangle is always 180 degrees.
Therefore, to find the measure of angle B, we can use the formula:
180 degrees = m<A + m<B + m<C
Given that m<A = 63 degrees and m<C = 99 degrees, we can substitute these values into the equation:
180 degrees = 63 degrees + m<B + 99 degrees
Rearranging the equation:
180 degrees - 63 degrees - 99 degrees = m<B
Simplifying:
18 degrees = m<B
Therefore, the measure of angle B is 18 degrees.
