Explanation:


Look the the 'to the power' above 10. The greatest number to the power is the greatest number. Here 6>4
Therefore, 
Answer:
ACD = 76
Step-by-step explanation:
The sum of the interior angles of a triangle total 180 degrees.
The sum of the two angles making up a straight line also total 180 degrees.
In the triangle, we have A + B + C = 180.
On the straight line, we have C +
= 180, so C = 180 - 
We now have A + B + (180 -
) = 180
A + B -
= 0
(4x + 15) + 21 - (7x + 6) = 0
3x = 30
x= 10
Therefore ACD = 7x + 6 = 76
