Question

If EBC = 31a - 2 and EBH = 4a + 45 find HBC

add the Digram also​

Answer 1

solution

EBC = 31a - 2

EBH = 4a + 45

HBC = 180 - (31a - 2) - (4a + 45)

HBC = 180 - 31a + 2 - 4a - 45

HBC = 180 - 35a - 43

HBC = - 35a + 137

Answer 2

EBC = 31a - 2

EBH = 4a + 45

HBC = 180 - (31a - 2) - (4a + 45)

HBC = 180 - 31a + 2 - 4a - 45

HBC = 180 - 35a - 43

HBC = - 35a + 137
