Answer:

Step-by-step explanation:

The triangle is an isosceles and so angle SRT and angle STR are equal

also:

Angle SRT and angle STU are supplementary so their sum is equal to 180

7x + 2x + 9 = 180 add like terms

9x + 9 = 180 subtract 9 from both sides

9x = 171 divide both sides by 9

x = 19

How do you solve: cos(x-π/3)=-1

gladu [14]

Answer:

x = $\frac{4\pi }{3}$

Step-by-step explanation:

given

cos(x - $\frac{\pi }{3}$ ) = - 1, then

x - $\frac{\pi }{3}$ = $cos^{-1}$ (- 1) = π

Add $\frac{\pi }{3}$ to both sides, hence

x = π + $\frac{\pi }{3}$ = $\frac{4\pi }{3}$
