Answer:
x = 25 degrees
Step-by-step explanation:
All angles in a triangle should add up to 180 degrees. So to solve for x, set up an equation where all three angles added up equals 180.
180 = 99 + 56 + x
180 = 155 + x
25 = x
The unknown angle is equal to 25 degrees.
Answer:
you end up with 75 divided by 3.
Step-by-step explanation:
75 divided by 3 - 8 + 8
add 60 and 15
3 - 2(4) + 2^3
multiply -2 by 4
3 - 8 + 2^3
multiply 2 by itself 3 times
3 - 8 + 8 (which gives you 3 again)
and you get 75 divided by 3
The rule for multiplying similar bases with exponents is:
(a^b)*(a^c)=a^(b+c)
In this case you have:
(x^9)(x^2)
x^(9+2)
x^11
Since we are looking for the principal amount, then all we have to do is reverse the process of getting the amount of tax. In order to get the principal, you just have to divide 22 with 0.05. The answer is 440 so that is the principal amount you are looking for.
