I think the correct answer is D. Or if not is B.
Answer:
7,387,128
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
If the ratio is 2:3 that means there are 2 boys and 3 girls because the sentence starts with BOYS to GIRLS meaning the number of girls come second
To be able to fine one of the bases we must first find the vertex and to do that we have to find the value of a.
A triangle measures 180 degrees.
Therefore we must form an equation that is equal to 180 degrees.
(a + 30) + 2(2a - 15) = 180
We put 2 in front of (2a - 15) because there are two base angles.
Solution:
(a + 30) + 2(2a - 15) = 180
a + 30 + 4a - 30 = 180
a + 4a + 30 - 30 = 180
5a = 180
5a/5 = 190/5
a = 36 degrees
Therefore the base = 2(36) - 15 = 57 deg
