Question

What is the value of x in the right triangle below? Round to the nearest tenth.

Answer 1

`{ \dashrightarrow{ \sf{ \green{ (x)/(18) = \sin(70) }}}} \\ \\ \\ { \dashrightarrow{ \sf{ \green{x = 18 \sin(70) }}}} \\ \\ \\ { \dashrightarrow{ \sf{ \underline{ \green{x = 18 * 0.77}}}}} \\ \\ \\ { \dashrightarrow{ \sf { \green{x = 18 * 0.939}}}} \\ \\ \\ { \dashrightarrow{ \sf{ \green{x = 16.9 }}}}`

Answer 2

• C. 16.9

Explanation:

Use sine:

• x/ 18 = sin 70
• x = 18 sin 70
• x = 16.9
