The number of blue marbles is
Is my answer right.
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
<B = 2x + 15
<B = 2*11 + 15
<B = 37 which makes your answer right
B. Is correct
37°
