Answer 1

Part d

For this case we have the following formula:

m

and we know that angle C and E are supplementary so then we have this:

m < C + m< E= 180

m < C + 5x +77 = 180

m < C= 103- 5x

And replacing we got:

6x +33 +7x -12 + 103- 5x = 180

And solving for x we got:

8x +124= 180

8x= 180-124= 56

x = 56/8= 7

Then we have:

m < A= 6*7 + 33= 75

m< B = 7*7 -12= 37

m < C = 103- 5*7= 68

m< E = 5*7 + 77= 112
