Answer:
x ≈ 21.7
I rounded to the nearest tenth because the values are given in tenths. The first few digits of x are below if you are rounding to something else, as the image is cut out.
Step-by-step explanation:
(It will not let me post, so I've attached a screenshot of my explanation:)
If you sketch the triangle, you need to understand that 12 is the length of opposite side (opposite to theta). Then the longest side is 13 is the hypotenuse. The other side with length 5 is the adjacent side. Thus from the definition of sin(theta)=opposite side/hypotenuse=12/13. A question for you, what is cos(theta)? cos(theta)=5/15 and tan(theta)=12/5
1 is wrong there are two numbers greater than 4 but less than or equal to 6.
the first one was correct
The least common denominator is 15. The equivalent fractions would be 10/15 and 12/15.
