I’m pretty sure it would be 0,5 but if not look up calculator soup and type your question and it should give you a whole list of everything equivalent to it!
The question said that it told you the base angles. A roof would have two equal base angles. The base angles= 53
All the angles of a triangle each 180, (the roof is shaped like a triangle)
So, let's make x the missing angle.
53(2)+x=180
106+x=180
Subtract 106 on both sides.
180-106= 74
The vertex angle is 74.
I hope this helps!

Answer:
<em>To find the Perimeter</em><em> </em><em>just </em><em>add </em><em>all </em><em>the </em><em>numbers</em>
<em>=</em><em>3f+3f+8+8+2f-1</em>
<em>=</em><em>8f+</em><em>1</em><em>5</em>
Well from what im gathering from your broken english and this ridiculously worded problem, here is how i see it.
15+2x=33
33-15=18, 18/2=9, 15+2(9)=33, 15+18=33, 33=33
x=9
