Cos(angle) = adjacent/hypotenuse
Cos(angle) = 1.5/10
Angle = arccos(1.5/10)
Angle = 81.37 degrees
Although the angle is close, it is over the 80 degrees, so the inspector should be concerned.
Answer
1.8/125 cm³
2. 13
3a. x³-17
3b. 3x-5
5. A) Power
Step-by-step explanation:
1. (2/5)³= 2/5 * 2/5 * 2/5
= 4/25 *2/5
=8/125
2. b³+(10-a)
= (2)³ + (10-5)
=(2*2*2) + (5)
= 8 + 5
= 13
3a. a number cubed = x³
seventeen less than = -17
3b. three times a number = 3x
five = 5
5. product is when two values are multiplied (13 and 3+x)
