To get the type of triangle mentioned we need to find the value of x first.
Sum of angles in a triangle add up to 180°, thus
2x+(3x-15)+(7x+15)=180
2x+3x-15+7x+15=180
12x=180
x=15°
thus the respective sizes will be:
2x=30°
3x-15=30°
7x+15=120°
Since the triangle has two congruent angles we conclude that the triangle is called Isosceles triangle
Answer:1/4 of is the correct answer d is the dependant variable.
Step-by-step explanation:
17500/5 = 3500 ( down payment )
17500 - 3500 = 14000
14000/100 = 140
140 x 4 = 560 ( CD account )
14000 - 560 = 13440
13400/100 = 134.4
