Answer:
54
Step-by-step explanation:
Answer:
8+x=2x-3
x=11
Step-by-step explanation:
Answer of 9 = 7 because those red arcs mean that both of those angles are the same, so if the angle on the right is 7, the angle on the left is 7
Answer of 11 = 60, because this is a equilateral triangle, which means all the sides are the same.
180 - 60 = 120 (180 is in the equation because all interior sides of a triangle add up to 180)
120 divided by 2 = 60
Answer:
248°
Step-by-step explanation:
y = 180°- 56°
= 124°
x = 124° because opposite angles of a parallelogram are equal
x + y = 124° + 124°
= 248°
