Answer:
Step-by-step explanation:
Since it is a right-angled triangle, we will apply Pythagoras Theorem.
<u>Given are:</u>
Base = 16
Perpendicular = x
Hypotenuse = 18
<u>Pythagoras Theorem:</u>
(18)² = (16)² + (x)²
324 = 256 + x²
Subtract 256 to both sides
324 - 256 = x²
68 = x²
Take sqrt on both sides
8.2 = x
x = 8.2

Answer: 44
Step-by-step explanation:
<R is an inscribed Angle- so if we follow it's ends to the intercepted Arc we are looking at arc NQ
the intercepted arc is 2 times the measure of the inscribed angle, so arc NQ is 44 (22*2)
<O has the same measure as the arc NQ so angle O is 44
Answer:
y^24
Step-by-step explanation:
a variable with an exponent has an exponent which is divisible by 3 then it is a perfect cube.
