The measures of the angles of a triangle are shown in the figure below. Solve for x.
2 answers:
(3x + 13) + (8x + 14) + 109 = 180°
(3x + 13) + (8x + 14) = 71°
11x + 27 = 71°
11x = 44°
x = 4
Answer:
x = 4
(3x + 13) = 25°
(8x+ 14) = 46°
Step-by-step explanation:
(3x + 13) + (8x +14) + 109 = 180 (Angles of a triangle)
11x + 136 = 180
11x = 180 - 136
11x = 44
x = 4
Substituting the value of x
(3x + 13) = 3×4 + 13 = 12 + 13 = 25
(8x + 14) = 8×4 + 14 = 32 + 14 = 46
