Answer:
x = 6
Step-by-step explanation:
because we know the lines intersect we also know the 2 angles are vertical meaning they are equal to each other
Knowing the angles are equal to each other you can make the equation
2x + 29 = 9x - 13
then you solve for x in this equation
2x + 29 = 9x - 13
(subtract 2x from both sides)
29 = 7x - 13
(add 13 to both sides)
42 = 7x
(divide by 7 on both sides)
6 = x
x = 6
Area of triangle = 1/2 x base x height
base = 15 + 6 = 21
height = 8
Area of triangle = 1/2 x 21 x 8 = 84 in²

Answer: Area = 84 in²
