we know that
An isosceles triangle has two equal sides and two equal angles
If the isosceles triangle is a right triangle
then
The measure of the angles are
so
we have
Substitute and solve for the hypotenuse
therefore
<u>the answer is</u>
Answer:
Step-by-step explanation:
Recall the following Pythagorean Identity:
Let's solve the x equation for cos(t) and the y equation for sin(t).
After the solve we will plug into our above identity.
x=5cos(t)
Divide both sides by 5:
(x/5)=cos(t)
y=5sin(t)
Divide both sides by 5:
(y/5)=sin(t)
Now we are ready to plug into the identity:
Multiply both sides by 5^2:
This is a circle with center (0,0) and radius 5.
All I did to get that was compare our rectangular equation we found to
where (h,k) is the center and r is the radius of a circle.
