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:
40
Step-by-step explanation:
Find the area of each side and add them together. The area of triangles equals Height time 1/2base so you get a=1/2(4)(3). A=6. 6+6+6+6=24 plus the base which is 4x4=16. 26+16=40
40 is our final answer
The answer is false.
There are only for operations for arithmetics.
Addition. Subtraction. Multiplication. Division.
