vtigers
The Angles Given
Form A Linear Pair So, They Add Up To 180
Form A Vertical Angle So, They Are Equal 
Form A Complementary and Supplementary Angles So, They Add Up To 90 and 180

Using Those Concepts Use A Formula 
All I Know Is <ABD and <BFC = 70 
<GBA = 115
<CBF and <ABE = 150

Solve The Rest, You Are Smart! Ok! Thanks!
