Question

Solve for x
650
35°
7x + 10

Answer 1

X= 10. ...................

Answer 2

x = 10

Explanation:

By interior angle sum property of a triangle:

65° + 35° + (7x + 10)° = 180°

100° + (7x + 10)° = 180°

(7x + 10)° = 180° - 100°

(7x + 10)° = 80°

7x + 10 = 80

7x = 80 - 10

7x = 70

x = 70/7

x = 10
