Is my answer right.

Answers

Answer:

Yes

Step-by-step explanation:

The two angles that are both acute (B and C in this case) add up to 90 degrees. That's because a right triangle has 1 angle that = 90 and every triangle has 180 degrees.

<B + <C + 90 = 180

<B + <C = 180 - 90

<B + <C = 90

Equation

2x + 15 + 5x - 2 = 90 Collect like terms

Solution

7x + 13 = 90 Subtract 13 from both sides

7x = 90 - 13 Subtract

7x = 77 Divide by 7

x = 77/7 Divide

x = 11 Substitute

<B = 2x + 15

<B = 2*11 + 15

<B = 37 which makes your answer right

B. Is correct

37°

Sally Ron and Jerry shared some large sandwiches that were the same size and cut into eighths Sally ate 5/8 sandwiches ron ate 7/8 sandwiches and Jerry ate 3/4 sandwiches who ate the most explain

Answers

The answer is Ron. First, you have to get a common denominator for the three fractions and the common denominator is 8. So 3/4 is equal to 6/8. Next, you compare the three fractions. 7/8 is larger than 5/8 because the numerator 7 is bigger than 5. 7/8 is bigger than 6/8 so 7/8 is larger than all the fractions. Therefore, Ron ate the most.

Ron, because if we see which fractions are largest

5/8
3/4=6/8
7/8
