Two complementary angles = 90°
X = 18+ 2y
X + y = 90
Plug first equation into second
18 + 2y +y = 90
18 + 3y = 90
18 – 18 +3y = 90 – 18
3 y = 72
3y/3 = 72/3
Y = 24
Plug y into 2nd formula
X + 24 = 90
X + 24 -24 = 90 – 24
X = 66

Answer:
0.29
Step-by-step explanation:
divide 4.69 by 16
this answer should give you 0.29
It was 210 cm.
The function she used is h(t) = 210 + 33t. This is a linear function, since it is of the form f(x) = mx+b. In a linear function, we have the slope, m, which tells us how much the height increases per year, and the y-intercept, b, which tells us how tall it was when we began measuring. Our m value would be 33 and our b would be 210, so the original height was 210.
