Question

What is x? i have gotten every other question before this no problem but i think i’m typing it wrong

Answer 1

13/2

**6.5 would NOT be acceptable because you can only enter integers or simplified fractions for that problem**

Explanation:

sin30° = opposite/hypotenuse (trig rules you need to memorize)

sin30° = x/13

Solve for x:

x = 13sin30°

sin30° = 1/2 (unit circle, gotta memorize this too)

so.. x = 13*(1/2)

x=13/2
