Use trigonometry
sin 42 = a / 21
a = 21 sin 42 = 14.05
Answer:
<h3>either way the answer is be =36 so the length of the missing side is 36 CM. </h3>
The slope is the coefficient of x when the coefficient of y is 1.
The slope is -0.5
The y-intercept is where x=0
y = 17 - 0.5 (0)
y = 17
The y-intercept is 17.
