What is the sine ratio for ∠C?

Question 1 options:

13/12

12/13

5/12

13/5

12/5

What is the cos ratio for ∠C?

Question 2 options:

8/6

8/10

6/10

6/8

10/8

1. 12/13

2. 6/10

Step-by-step explanation:

SinC = opposite/hypotenuse

sinC = AB/AC

sinC = 12/13

cosC = adjacent/hypotenuse

cosC = BC/AC

cosC = 6/10 = 3/5

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
