Question

Find the measure of the indicated angle.

A) 145
B) 35
C) 67
D) 78

Answer 1

53

Explanation:

The sum of all the angles in a triangle is 180. Now, let's figure out angle C.

180-145=35.

Currently,

A=5x+2

B=6x

C=35

Then, 180-35=145, which is the combined angle of A and B. First let's set the 2 degrees aside for a bit, so we can figure out x.

145-2=143. 143/(5+6) = 143/11 =11. Now we know X = 11.

Now, we work to find angle A. 5*11+2 = 55+2 = 53

I think this is the correct solution.
