Answer:

-4/5

Step-by-step explanation:

3/5+(-7/5)

Since there are a + sign and a - sign next to each other, they cancel out to make a - sign.

3/5 - 7/5

Now, we can subtract.

3/5 - 7/5 = -4/5

Hope this helps! :)

PLEASE HELP!
leva [86]

Answer:

B. 56°

Step-by-step explanation:

We are given that m∠R is 66° and m∠T is 122°.

We can apply the supplementary rule since ∠S and ∠T are a linear pair. So, we can use ∠T to find ∠S through 180° - 122° = 58°.

Now, we can use ∠R and ∠S to find ∠Q.

66° + 58° = 124°

180° - 124° = 56°
