<h3>
Answer: 5</h3>
Explanation:
Plug z = 9 into the second equation and solve for x.
x/z = 2/3
x/9 = 2/3
x = 9*(2/3)
x = 18/3
x = 6
This leads to
xy = 30
y = 30/x
y = 30/6
y = 5
Answer:
x = 63.7°
Step-by-step explanation:
Since the triangle is right we can use trig. ratios to solve
tan x° =
= 
⇒ x =
(
) = 63.7°
80/100 also eighty out of a hundred.
