Answer:
x=7 (if your teacher cares it could + or - 7)
Step-by-step explanation:
Okay, since it's a 90 degree triangle you can use the Pythagorean theorem
( a^2 + b^2 = c^2)
Since it's an isosceles triangle the other side is x because it's the same value.
x^2 + x^2= (7 )^2
Add the left side
2x^2= 7^2 + ^2 roots and square roots cancel each other out
So -> 2x^2= 49 x 2 =98
just solve for x.
x^2 = 98/2
x^2= 49
Square root both sides
x= 7
Answer:
Step-by-step explanation:
Change the given equation to slope-intercept to get . When you multiply the slopes of perpendicular lines, you get -1. -1 divided by
is
. The slope of the new line is then
. The perpendicular line passes through (5, 5) so you can have the equation
. Simplifying gets
. So now the final equation for the perpendicular line is
