Answer: angle 1=129 degrees
Step-by-step explanation:
180 - 99 - 30 = 51
all the angles of a triangle should add up to be 180 degrees
51+99+30=180
angle 1 is supplementary to the angle that is 51 degrees so it would be 129 degrees. 180-51=129

Answer:
8,9
Step-by-step explanation:
(x +1) + 7=2x
x+8 = 2x
8=x
<span>At simple interest:
10% = 5,000, 000 x 10/100 = 5,000,000 x (1/10) =$500,000
spread over 8 years = 8 x $62,500
monthly interest payment = $62,500/12=$5208.33
Smart decision: has to at least break-even, if not generate more than the total interest repayment. </span>
All internal angles in a quadrilateral add to 360
so
x+110+110+70=360
x+290=360
minus 290 both sides
x=70 degrees
