M∠6 is (2x – 5)° and m∠8 is (x + 5)°. Parallel lines q and s are cut by transversal r. On line q where it intersects with line r, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 1, 2, 4, 3. On line s where it intersects with line r, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 5, 6, 8, 7. What is m∠3?

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
