Answer:9 is the only one
Step-by-step explanation:
Answer:
(a, b, c, d) = (101°, 79°, 83°, 97°)
Step-by-step explanation:
∠a is the supplement of the one marked 79°, so is ...
∠a = 180° -79°
∠a = 101°
__
∠b is a corresponding angle to the one marked 79°, so is congruent to it.
∠b = 79°
__
∠c is a vertical angle with the one marked 83°, so is congruent to it.
∠c = 83°
__
∠d is a same-side interior angle between two parallel lines, so is supplementary to ∠c.
∠d = 180° -83°
∠d = 97°
Answer:
C
Step-by-step explanation:
Add 10x to both sides:
-10x - 135 = 117 + 2x
-10x - 135 + 10x = 117 + 2x + 10x
-135 = 117 + 12x
Subtract 117 from both sides:
-135 - 117 = 117 + 12x - 117
-252 = 12x
Divide both sides by 12:

-21 = x
So the answer is C.
Hope this helps!
A circle is 360 degrees, so 360/12 = 30 degrees.
Answer:
Yes, the quotient will be the same
Step-by-step explanation:
we know that
If the numerator and denominator of a fraction be both multiplied by the same number, the quotient will not be altered
Because is the same that you multiply the fraction by 1, and remember that when you multiply by 1, you always get your original number

therefore
Yes, the quotient will be the same
