Answer:
(in order) #1
for the first one you have a vertical angle. Vertical angle is basically any 2 lines who intersect each other. The opposite sides will be congruent.
So in this case
2x+8 and 110 are oppostie sides.
2x+8=110
Which is x= 51
#2
For the second one you have supplementray angles
Now for supplementary angles its basically 2 angles added up that form a straight line And 180 degress is always the measure of a straight line. SO in this case we do
9x+12x+75=180
Which is x=5
#3
This is also a vertical angle pair and their congruent just like #1
So 5x+5=65
x=12

7^4 is basically 7x7x7x7so 7x7=49x7=343x7=2401
4.3^3 same thing 4.3x4.3=18.49x4.3=79.507
The expression: B+5x2
<span>1/6 of 54 = 9 and 1/3 of 21 = 7
<span>so, 1/3 of 21 is smaller than 1/6 of 54.
Hope this helps :) </span></span>
