Since we need an angle measure we have to use an inverse trig ratio, sin^-1, cos^-1, or tan^-1.
Setting up the right triangle we have the opposite and adjacent so we use tan.
tan angle = 28/32
tan^-1 (28/32) = 41 degrees
The measure of arc LMN = 2 mesure of angle LMN ==> 64°
Given side 28 is equal to side 4
28÷4=7
therefore times all numbers on smaller shape by 4 to get sides of larger shape, add the numbers on larger shape together to equal 238
Perimeter of larger shape is 238
Answer is 960 are is Lengthx Width. I believe
