The base angles of an isosceles triangle are equal
The base angles are 15 degrees, while the vertex angle is 150 degrees
The base angles are given as:
Base = (6a- 3) and (a + 12)
So, we have:

Collect like terms


Divide both sides by 5

Substitute 3 for a in Base = (6a- 3),



So, the base angle is 15 degrees.
The vertex angle is calculated using:

So, we have:


Hence, the vertex angle is 150 degrees

Answer:
15%
Step-by-step explanation:
Since a percent is out of 100 we can make 75/500 to have the denominator of 100.
To do that you divide
500/5 = 100
and for the numerator
75/5 = 15
whatever you do to one side you must do to the other that's why I divided both sides by 5. The ending fraction would be 15/100 which is the same as 15%
Hope that helps and have a great day!
