5a+3b = 24 
(5+a)(3+b) = 49 

The order of steps are different because one requires multiplication then addition while the other one requires addition then multiplication. But one sure thing is that they both need substitution.

All triangle angles have 60 degree angles. What are the side lengths?
Alex_Xolod [135]
If all the angles are 60 degrees, this is an equilateral triangle. This means that all the sides have the same lengths. Whatever length side a is, b and c have the same length. 

Hope this helps :)

Please find the missing side of this triangle
Strike441 [17]
The answer is 15.01

First you need to find the other angle of the triangle so you do 90+25 which gives you 115 and subtract that by 180 because all angles of a triangle add up to 180. That gives you 65 then you will use TAN(65) and get 2.144506920509559 which you will then multiple by 7 to get 15.01154844356691 which you then round to get 15.01!
