That both 2 angles of the triangles are not equal to the third angle... the third angle is most likely bigger because it would not exactly be a triangle if it wasnt
Keep in mind that:
- the sum of the interior angles of every triangle in existence is 180 degrees
- the base angles of isosceles triangles are congruent
With this information, I have created a diagram. I encourage you to always draw a diagram when you can - it aids in the solving process.
Now, to find <em>a</em>, set the measures of the interior angles equal to 180.
(<em>a</em> + 15) + 7<em>a</em> + 7<em>a</em> = 180
Solve for <em>a</em>.
<em>a</em> + 15 + 7<em>a</em> + 7<em>a</em> = 180
15 + 15<em>a</em> = 180
15<em>a</em> = 165
<em>a</em> = 11
Find the angle measures by plugging 11 for <em>a</em>.
<em>a</em> + 15
(11) + 15
26
7<em>a</em>
7(11)
77
Check your work by adding the angles measures.
77 + 77 + 26 = 180

Answer:</h3>
<em>a</em> = 11
Each base angle measures 77 degrees and the vertex angle measures 26 degrees.
