You can't unless something is missing in your question.

Sally is 10. To solve: Let's use as variables the letter j for Joe's age today and s for Sally's age today, and try to solve for s. Start by expressing what we know about the relationships of Joe's and Sally's ages as equations. Joe (today) is 5 years older than Sally (today): j = s + 5 Joe in 15 years will be 3 times Sally's age (today): j + 15 = 3s Begin solving the two equations simultaneously by replacing the j in the second equation with its value from the first; then solve for s: j + 15 = 3s s + 5 +15 = 3s [since j = s + 5] s + 20 = 3s 3s = s + 20 [just reversing the equality] 2s = 20 [subtracting s from both sides] s = 10 [Your answer! Sally's age today.] Now solve for Joe's age today (j), and check the answer: j = s + 5 [given] j = 10 + 5 [substituting the solved age for Sally] j = 15 [Joe's age today!] Checking we see that Joe's age is 5 more than Sally's; and we see that in 15 years, Joe's age of 30 is 3 times Sally's age today of 10. Success!
L = S + 11; 2S + 3(S + 11) = 123, ie 2S + 3S + 33 = 123ie 5S = 90 ie S = 18 and L = 29
Cryptogram said 45, but what was the question?There is no punctuation, except for the last "?", so I will assume that when a word is capitalized, it starts a new sentence. Therefore the statements are:In a triangle the measure of the largest angle is 3 times the measureof the smallest angle. The measure of the remainingangle is twice themeasure of the smallest angle.Since "Measure of the largest angle" is a fragment of something, I will discard it (it could be a mistake of leftover text or could be an incomplete thought). I guess that the "?" at the end means that we are supposed to answer something, and the answer could possibly relate to the largest angle. If I supply all the angles, you will hopefully get your answer.Since L=3S and M=2S, and 3S+2S+S=180º, then 6S=180º, so Smallest angle =30ºMiddle angle =60ºLargest angle =90º
