Answer:
A
Step-by-step explanation:
Answer : A {-8}
-4 = b/2
-4 *2 = b
-8 = b
To find the side length of a cube with a volume of 343, you need to find m to the third power. Solve that and you get 7. m = 7
Answer:
50
Step-by-step explanation:
-5(-10) = x/-10 (-10)
50 = x
Answer:
Arc DE = 90°
m<GAB = 82°
Arc DC = 49°
Step-by-step explanation:
Given:
m<EAF = 74°
m<EAD = right angle = 90°
Arc BG = 82°
Required:
Arc DE,
<GAB, and
Arc DC
Solution:
Recall that the central angle measure = the intercepted arc measure.
Therefore:
✔️Arc DE = m<EAD
Arc DE = 90° (Substitution)
✔️m<GAB = arc BG
m<GAB = 82° (Substitution)
✔️Arc DC = m<CAD
Find m<CAD
m<CAD = ½(180 - m<GAB)
m<CAD = ½(180 - 82)
m<CAD = 49°
Arc DC = m<CAD
Arc DC = 49°
