Question

Need help ASAP!!! This is due by tomorrow

Answer 1

a = 17

Explanation:

This seems to be an equilateral triangle, so the angle is 60 degrees. 68 - 8 is 60. 4a represents 4 × a, and we know 4 × a has to be 68. 68 / 4 is 17, meaning a = 17.

Answer 2

a= 17

Explanation:

Since all sides are equal length, all angles must be equal. Since all of the angles of every triangle sum to 180*, 180/3= 60*. Therefore, (4a-8)*=60*

From there, we can solve for a by adding 8 to both sides:

(4a-8)+8=60+8

4a=68

Then we can divide both sides by 4 to get

(4a)/4= 68/4

a=17
