Eighteen could be in standard form 18 or expanded form 10 + 8.
14 20
---- = ----- cross multiply
3x x-5
14(x-5) = 3x (20)
14x - 70 = 60x
-14x -14x
-70 = 36x
/36 /36
-70/36 = x
or
-35/18 = x
1. x=4, y=0
3. x=2.6666, y=0.3333
The answer is 24° because all three the three angel of the triangle is 180° and u subtract 132 by 180 left with the other two small angel's sum which is 48. rhan u divided by two u get one of the angel which is 24°.
im pretty bad at explaining, hopefully it helps!
