Answer:
x = 63, y = 27
Step-by-step explanation:
x and 117 are adjacent angles and sum to 180°
x + 117 = 180 ( subtract 117 from 180 )
x = 63
x and y sum to 90°
x + y = 90
63 + y = 90 ( subtract 63 from both sides )
y = 27
Answer:
56^6
Step-by-step explanation:
when they are the same exponent
you just add the coefficients
KE=1/2(m)(v)^2
KE=1/2(80)(1.5)^2
KE=90 J
