Answer:
5/7 I got this one it was 5/7
Answer:
vertical angles
∠1 and ∠3 are vertical angles. Their measures are equal, so m∠3 = 90 . ∠1 and ∠2 are supplementary.
Step-by-step explanation:
Remember in every triangle, the sum of the angles adds to 180 degrees. So let us call the smallest angle's measure "A". The largest angle is 3A and the third angle is A+10. So A + 3A + (A + 10) = 180.
<span>Well a simply way is to look at the problem as
Term 1 | 2 | 3 | 4 | 5 ----------------------------
Value | 9/2 | | | 6
There are 3 terms from 2 to 5 and the value increases 6 - 9/2 = 3/2 so the common difference is 3/2 divided by 3 so the common difference is 1/2 so to find the 3rd term add 1/2 to the 2nd term the pattern is each term is increasing by 1/2.. or 1/2 is added to the previous term. </span>
