Example:The missing value is x than Sin 7 / 18
Sin x = 0.4
x = Sin-1 0.4
x = 23.6*
Answer = 23.6*

Solve: QR = 4 ; PR = 17 ; PQ = 12, Sin __?___ = 12 / 17

44.9

Step-by-step explanation:

12/17 = PQ/PR

(sin^-1)(12/17) = 44.9

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
