Answer:
Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle =
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* =
90* = 10
x intercept is -5
Explanation
Step 1
find the slope of the line:
when you know 2 points of the line, you can find the slope, by using:
then,Let
P1(33,-22)
P2(52,-33)
replace,
Step 2
find the equation of the line
let
replace,
now, we have the equation of the line, to get the x intercetp ( it is when y=0)
replace
so, the x intercetp is -5.
I hope this helps you
