What is the value of x? 50 pts! enter your answer in the box.

Solve for RT.

sin(60) = RS/RT

RS/sin(6) = RT

(2√3)/(√3/2) = RT

4 = RT

Solve for RQ.

tan(45) = RQ/RT

tan(45) = 1

RQ = 1 * 4

RQ = 4

Best of Luck!

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
