Answer:

x = 10°

Step-by-step explanation:

The diagonals of a rhombus divide the figure into congruent right triangles. That means the two marked acute angles are complementary.

<h3>solve for x</h3>

Complementary angles total 90°, so the relation we can use to find x is ...

(3x -13) +(8x -7) = 90

11x = 110 . . . . . . . . . add 20

x = 10 . . . . . . . . . divide by the coefficient of x

The value of x is 10°.

An equation is shown below:

lisov135 [29]

Answer: x = 1

Step-by-step explanation:

5 ( 2x - 8 ) + 15 = -15 (write the equation)

5 ( 2x - 8 ) = -30 (subtract by 15 on both sides)

2x - 8 = -6 (divide by 5 on both sides)

2x = 2 (add 8 to both sides)

x = 1 (divide by 2 on both sides)

Answer:

Required equation is y - 36 = (24 - 36)/(2 - 1) (x - 1)

y - 36 = -12(x - 1)

y - 36 = -12x + 12

12x + y = 12 + 36

12x + y = 48
