Ok, we know that there are 270 degrees in a triangle, so just add 49+57, the you'll get 106, 270-106=164. ANSWER: 164
The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50
