Answer:
it's 20
Step-by-step explanation:
(X+5)° + (7x-5)° + x°= 180° { sum of the three angles of the triangle is 180°}
X+5+7x-5+X = 180
X+7x+X+5-5= 180
9x+0 = 180
9x = 180
therefore X= 180/9
= 20
All angles are of triangle and thus give sum of 180⁰
x + 5 + 7x - 5 + x = 180⁰
9x = 180⁰
x = 20⁰
It's false because it's actually about 75%.
From 15-45 is 3/4 of the plot
