The sum of all the angles in a triangle should always add up to 360° and seeing that this is an isosceles triangle 2 of the angles should be equal.
So there would be 2 30° angles and 360-60=300 so the 3rd angle would be equal to 300° . Hope this helps!

Step-by-step explanation:
Given
<u>Circle C</u>
--- radius
--- center
<u>Circle E</u>

--- center
Required
Prove their similarity
Translate circle C 8 units up;
The rule is:

So, we have:


Translate circle C' 7 units right;
The rule is:

So, we have:


<em>At this point, both circles now have the same center at (4,9)</em>
The next step is to dilate circle E by 4/3
This will only affect radius and not the center of E
The rule is:



So, we have:
-- equal radii
--- equal center
