Answer:

m = 6

Step-by-step explanation:

Here, we want to find the value of m

To do this, we use the indices addition property for multiplication

On the left hand side;

5^(2 + m + 7) = 5^15

5^(m + 9) = 5^15

since the bases are equal, we equate the powers

m + 9 = 15

m = 15-9

m = 6

</span><span>All angles are 60 degrees.
2/3h=r
2/3h=6
h=9
 
You have a right triangle therefore you can calculate the base as (9tan30)=sqrtof3 over 3
 
Area of triangle 1/2 bh = 1/2(sqrt3 over 3)

(9) As this is just 1 triangle you then need to multiply it by 2

bh = sqrt of 3 over 3 * 9</span><span>
