Solve for x and y
60°
у
Х
30°
73

x=7

y=14

Step-by-step explanation:

this is a special 30-60-90 right triangle bc there is a right angle marker and a 60 degree and 30 degree angle

in 30-60-90 right triangles the short leg is x, the long leg is x√3, and the hypotenuse is 2x

it is given that the long leg is 7√3, and since the long leg equals x√3, then x equals 7

so the short leg, x, is 7  and since the hypotenuse is 2x, 2(7) =14

20p+22p-12p=90
as all of the terms on the left are 'p's then we consider them to be called like terms. When we have like terms we can add or subtract freely.
so:
20p+22p-12p=90
20p+22p=42p
42p-12p=30p
therefore we get:
30p=90
this is the same as
30*p=90
to find do we need to 'work backwards' to move the 30 to be with 90.
So to 'work backwards' we do the opposite of multiply and divide it instead to both sides of the equation.
30/30*p=90/30
p=90/30
p= 3
