Answer:
x = 5
Step-by-step explanation:
6/18 = x/(20-x)
1/3 = x/(20-x) Multiply both sides by 20-x
(20-x)/3 = x Multiply both sides by 3
20-x = 3x Add x in both sides
20 = 4x Divide both sides by 4
5 = x
Answer:
x = 40 and y = 70
Step-by-step explanation:
This is an isosceles triangle since the two sides adjacent to the x angle are the same length. The angle opposite the 110 is 70 since these are supplementary angles. Angle y is 70 (isosceles triangle has two sides equal and two angles equal). The sum of the interior angles of a triangle is 180, so x = 180 - 70 - 70 = 40.
