Its the additive identity prosulate
C because one x-value can ONLY have one corresponding y-value. It cannot have more than one.
Answer:
x= 40
y= 20
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 60 = 20 sqrt(3) / x
x = 20 sqrt(3) / sin 60
x = 20 sqrt(3)/ (sqrt(3) /2)
x = 20 *2
x = 40
cos theta = adj / hyp
cos 60 = y/x
x cos 60 =y
40 * 1/2 = y
20 =y
36 because 55 divided by 5 equals 11 and 11 x 2 = 22 and 35 ÷ 5 equals 7 and 7× 2 equals 14 and 14+22=36
