Answer:
2 or maybe 1
Step-by-step explanation:
there is angle then side (line) and then another angle.
X=-4 is the answer because all of the points of the line are x=-4
The sum of the interior angles of a triangle is 180 so to find x your equation would be (x+15)+(2x-20)+(2x)=180...once you solve this equation x should be 37...and now you just plug in 37 for x and solve for the angle measurments....(37+15)=52....(2(37)-20)=54....2(37)=74

Answer:
A. 2
Step-by-step explanation:
The perimeter is the sum of the side lengths:
48 = (3t +3t) +(4t +4t) +(7t +6)
42 = 21t . . . . . . . . . . . . . . . . . . . collect terms, subtract 6
2 = t . . . . . . . . divide by 21
