Alright, lets say the measure of the 3rd angle (the smallest one) is  x degree, then measure of the 1st angle will be (x + 25) degree, and 2nd one: 3x degree. The sum of all the angles in any triangles is 180 degrees.

(x + 25) + 3x + x = 180

5x + 25 = 180 ---> 5x = 180 - 25 ---> 5x = 155 ---> x = 155/5 ---> x = 31o (third angle)

31 + 25 = 56o (first angle)

3 × 31 = 93o (second angle)

56 + 93 + 31 = 180

PLEASE HELP if Suzy can drive 4/5 miles in a half hour how many miles can she drive in 1 hour FOR A TEST PLEASE ANSWER
kati45 [8]
Since you are trying to figure out how many miles she can drive in 1 hour and you already have half of that hour, all you would need to do is double that number. 
\frac{4}{5} × \frac{2}{1}= \frac{8}{5}

Now, all you would need to do is simplify the answer.
\frac{8}{5} = 1 \frac{3}{5} or 1.6

The answer would be, Suzy can drive 1 \frac{3}{5} or 1.6 miles in 1 hour. 

I hope this helps!
