Question

The measures of the angles of a triangle are shown in the figure below, Solve
(5x+6)
54°

Answer 1

Explanation:

54+90+5×+6=360

so add like terms

54+90+6=150

150+5×=360

5×=360-150

5×=210

--- ----

5 5

×=42

Answer 2

Explanation:

90+54+(5x+6)=180...(sum of angles of a triangle)

144+5x+6=180

1. 5x=180-150
2. 5x/5=30/5
3. x=6
