I'm sorry but I do not know how to do this
STEP 1:
Triangles= 180°
Other Angles= 7:13= 7x + 13x
Add all the angles to equal 180°
140° + 7x + 13x= 180°
combine like terms
140° + 20x= 180°
subtract 140 from both sides
20x= 40
divide both sides by 20
x= 2
STEP 2:
substitute x value to find other two angles
7x= 7(2)= 14° one angle
13x= 13(2)= 26° other angle
CHECK:
140° + 14° + 26°= 180°
140 + 40= 180
180= 180
ANSWER: The other two angles measure 14° and 26°.
Hope this helps! :)
