Answer:
x = 5
arcEF = 58degrees
arcGH = 55degrees
Step-by-step explanation:
Find the diagram attached
The sum of angle on the straight line EH is 180degrees
Hence arcEF+ arcFG + arcGH = 180
10x+8 + 67 + 11x = 180
21x + 75 = 180
21x = 180 - 75
21x = 105
x = 105/21
x = 5
Since EF = 10x+8
arcEF = 10(5) + 8
arcEF = 50+8
arcEF = 58degrees
Also, arcGH = 11x
arcGH = 11(5)
arcGH = 55degrees
Answer:
C and D
Step-by-step explanation:
Additions have distributive property so the parentheses will not change the answer
Answer:
the radius is about 14.47 ft
Step-by-step explanation:
658=pi*r^2 Given
658=3.14*r^2 Substitution
209.55=r^2 Division property of equality
√209.55=√r^2 square root property of equality
the radius is about 14.47 ft
Answer:
Sets D, E
Step-by-step explanation:
Sets D and E both have repeated x-values , thus making them a relation not a function.
