Find the angles a,b,c and d
I am Lyosha [343]

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°

-10x - 135 = 117 + 2x<br> A. 25<br> B. -18<br> C. -21<br> D. 22 <br> Helps pls
Lina20 [59]

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:

\frac{-252}{12} = \frac{12x}{12}

-21 = x

So the answer is C.

Hope this helps!

Would the quotient be the same if you multiply by numerator and the denominator by 100? Explain
tamaranim1 [39]

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

\frac{a}{b}(\frac{100}{100})=\frac{a}{b}(1)=\frac{a}{b}

therefore

Yes, the quotient will be the same
