Hi there! To measure the angles, it’s best to have a protractor at hand. In terms of angles, complementary angles equal 90 degrees and supplementary angles equal 180 degrees. I could do this for you, but the angles aren’t always drawn to scale and it’s best to measure the angles out first before you do the other steps.
Answer:
B. (x+64)(x-64)
Step-by-step explanation:
x²- 64 = (x) ² - (8) ² =
(x+64)(x-64)
Answer:
Grace is right
Step-by-step explanation:
91 x 0.30 = 27.3
91 plus 27.3 equals to 118.3
Answer:
angle DEG=47+30(sum of two interior opposite angle is equal to the exterior angle formed)
DEG=77 degree
DEF+47+30=180(being sum of interior angle of a triangle)
DEF+77=180
DEF=180-77
DEF=103 degree
measure of each angle is 60 degree
