Answer: 135, 45, and 135 are the three other angles
==================================================
Explanation:
For a parallelogram, we'll have opposite angles with the same measure. So if one angle is 45 degrees, then the opposite angle is also 45 degrees. The other two angles are 180-45 = 135 degrees each. Adjacent angles in a parallelogram add to 180 degrees.
Answer:
Yes
Step-by-step explanation:
If the the trapezoid is Isosceles, meaning the legs, or the line segments connecting the bases are equal.
33 +4x = 513
4x = 480 (x = 480/4: x = 120)
Answer
Step 2 Divide each side by 4
0.25 = 1/4, 0.8 : 4 = 0.2
