Answer:
x=39
Step-by-step explanation:
First I try to find the angle measurements for the rest of the angles inside the triangle. I saw that the 68 degrees and I notice that it was vertical angles, meaning that the inside is also 68. I then notice that the 107 and the other unknown angle besides x must be 180 when adding up, so I can do 180-107=73. Now I know that that angle is 73 degrees I can find x by solving this equation 180=73+68+x, which the answer comes out to be 39. so x=39.
Hope this helps you
Answer:
The answer is false
Step-by-step explanation:
" An event is certain if its probability is 100% "
Statistics is about probability of occuring of an event; you cannot buy 100% certainty. Statistics is about managing risk.

Hence the statement is FALSE.
Answer:
120
Step-by-step explanation:
75-15=60. (Edit) Just realized that she spent her allowance that week, so it would be 120 because you need to multiply.
Difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
25=5^2
x^2-5^2=(x-5)(x+5)=0
set to zero
x-5=0
x=5
x+5=0
x=-5
x=5 or -5
A
Concurring that the other one made a mistake.
