Answer:

45/51

Step-by-step explanation:

SOH CAH TOA

Sin x = Opposite/hyp

Cos x = Adjacent/hyp

Tan x = Opposite/Adjac

Here we're looking for Sin R, so we want to find opposite side over the hypotenuse.

Thus, sin R = \frac{45}{51}

Answer:

x =  25        B = 65˙       C = 50˙

Step-by-step explanation:

Triangle Sum- All three angles in a triangle add up to 180˙

65 + (3x - 10) + (2x) = 180

65 - 10 +3x + 2x = 180                              Combine like terms

            55 + 5x = 180                               Move the 55 over to combine w/180.  

          <u>- 55            -55   </u>

                     <u>5x</u> = <u>125</u>                               Divide by 5

                      5       5                                

                       x =  25                               Answer

    B                                                   C

(3x - 10)                                           (2x)

(3*25 - 10)                                     (2* 25)

      65˙                                            50˙
