Answer:
59°, 71°
Step-by-step explanation:
This is a "sum and difference" problem. All problems of this type have the same answer: the larger of the two numbers is the average of those given.
Then the larger angle is (130 +12)°/2 = 71°. The smaller is 71° -12° = 59°.

There are several ways to get there using equations. You can, for example, let L represent the larger number. Then L - D will be the smaller one (where D represent the difference). The sum of the two numbers (S) is ...
L + (L -D) = S
2L = S + D . . . . collect terms, add D
L = (S+D)/2 . . . the larger number is the average of the sum and difference
For a two-digit number to be palindromic, the two digits must be the same.
Number of two-digit numbers with the two digits equal is 9. (i.e. 11, 22, 33, . . . )
Total number of two-digit numbers is 90.
Therefore, the <span>probability that a randomly chosen two-digit number is palindromic is 1 / 10 or 0.1.</span>
