Answer:
x =4
Step-by-step explanation:
sum of angles in a triangle = 180
(equilateral triangle) all sides are equal
180 ÷ 3 = 60
10x+20 =60
10x = 60 - 20
10x = 40
10x ÷10 = 40÷ 10
x = 4

Answer:
Option A) is correct.
Step-by-step explanation:
The final cost of a sale item is determined by multiplying the price on the tag by 75%.
So. if the final cost is represented by $F and the price on the tag is $t, then the relation between F and t will be
F = 0.75t.
This relation is linear since the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
Therefore, option A) is correct. (Answer)
