Math-way is a really good site for these kinds of problems i would recommend it if you need anymore help with stuff like this. :)
Step-by-step explanation:
Answer:
y = 30
x = 60
Step-by-step explanation:
4y and 2y are consecutive angles, which means they are equal to 180° when added together
that is the same with x and (5x - 180)
to solve, you set the equations to 180
solving:
4y + 2y = 180
6y = 180
y = 30
x + 5x - 180 = 180
6x = 360
x = 60
Did you notice the little box with corners marked in the angle down at the bottom ?
That angle is a right angle, and <em>this triangle is a right triangle</em> !
This piece of information is a big help. It breaks the problem wide open.
You know that in order to find the longest side of a right triangle . . .
-- Square the length of one short side.
-- Square the length of the other short side.
-- Add the two squares together.
-- Take the square root of the sum.
One short side=48. Its square = 2,304.
The other short side=48. Its square = 2,304.
Add the two squares: 2,304 + 2,304 = 4,608
The square root of the sum = √4,608 = <em><u>67.88</u></em> (rounded)
