Answer:
C
Step-by-step explanation:
it's an acute angle so it has to less than 90 and 71 just seems like it's too much
I typed right on the problem set.
Step-by-step explanation:
Right angle = 90°
(x + 3) + (x - 1) + (x + 1) = 90
3x + 3 = 90, x = 29.
Supplementary angles = Angles that add up to 180°.
x + (x + 104) = 180
2x = 76, x = 38.
Answer:

Step-by-step explanation:
The exponent of positive 1/2 is the square root of 60
60 ^1/2 = 
(−2)³ = (-2)(-2)(-2)
Note that:
two negative numbers multiplied together results in a positive
one negative and one positive number multiplied results in a negative
Multiply:
(-2)(-2) = 4
4(-2) = -8
-8 is your answer
hope this helps
