Angle e = x angle d = 5x supplementary means they add up to 180
x + 5x =180
6x = 180
6x/6 = 180/6
x = 30
so angle e = 30 and angle d = 5(30) = 150
Answer:
1
Step-by-step explanation:
Easy because whenever the exponent is 0 the answer must always be 1 then the exponent on the outside it would still be 1.
parallogram it has exactly 2 pairs of congruent angles
Answer:
13 and 77 degrees
Step-by-step explanation:
Complementary = 90 degrees
Set an angle to x
x+(x+64)=90
2x+64=90
2x=26
x=13
angle measures: 13, 77 degrees
Take 3/5 of 485 you got it
