Supplementary angles are two angles that add up to 180° degrees. • Complementary angles are two angles that add up to 90° degrees. • Adjacent angles share a vertex and a common side. • Congruent angles have the same measure. • An obtuse angle triangle has one angle that is greater than 90 degrees. • A triangle with angles 45°, 45°, and 90° would be a Isosceles triangle

answer: what

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
