Complementary angles are two angles whose measures add to a sum of 90 degrees. This can be expressed as the following formula:
A1 + A2 = 90
Substitute any known values into the equation above:
(2x + 1) + (x – 7) = 90
2x + 1 + x – 7 = 90
Combine like terms:
3x – 6 = 90
Add 6 to both sides of the equation:
3x = 96
Divide 3 from both sides of the equation:
x = 32
When (2x + 1) and (x – 7) are complementary, “x” is equal to 32.

Answer:
A
Step-by-step explanation:
(3+6)/(9+11+3+6)
= 9/29
Ok so the P means probability and on the first one c is 1 of 3 of the total number of of letters in the spinner, and so is g
What that means is that they both have 1/3 probable chance of getting picked or 33.3% but it is most likely asking for a fraction so use 1/3
For 5 it’s more difficult
What you have to do is find the probability of heads and tails
Which is 1/2
D is 1/3
And the vowels are A and E which is 2/3
So you would multiply all the fractions and your answer would be ( work; 1/2 x 1/3 x2/3=) 1/18
