The three angles on top are supplementar. This means that

So, the angles of the triangle are x, 72 and 73. Again, we know that the sum of the interior angles of a triangle is 180, so we have something similas as before:

So, the measure of angle x is 35.
(x +3)^2 = 49
(x +3)^2 = 7^2
so
x + 3 = 7
x = 4
and
x+3 = -7
x = -10
answer is C.
x = 4 and x = -10
Answer:
(4, -22)
Step-by-step explanation:
1. Identify the coefficients 2. substitute the coefficients into the expression 3. Solve the equation 4. Evaluate the function for x=4
Principle: divide the correct possibilities by the total nr. of possibilities to find the probability.
6. P(green) = 5 / (7+5+6) = 5/18
7. P(red) = 6 / 18 = 1/3
8. P(not green) = P(red | blue) = (6+7)/18 = 13/18
9. P(HH) = 5/25 = 1/5
10. P(HT) = 16/25
11. P(NOT TT) = P(HH | HT) = (5+16)/25 = 21/25
12. P(HH | TT) = (5+4)/25 = 9/25
13. P(5) = 1/6. P(H) = 1/2. P(5 & H) = 1/6*1/2 = 1/12. If you draw all the possibilities, you'll find there are 12. One of them is 5 & Heads.
