Answer:
5
Step-by-step explanation:
Since this is a right triangle we can use trig functions
sin theta = opp /hyp
sin 30 = x / 10
10 sin 30 = x
10 * 1/2 = x
5 =x
Answer:
For the first picture, 57.14
For the second picture, 27.04
This is in slope-intercept form, y=mx+b. m is the slope (b is the intercept). So the slope here is 8.
