There's no axis of symmetry in a house, no way to rotate it a little bit without changing it. There is plane symmetry, two different ways, the one shown in the last choice, and one through the center of the front and back.
Answer: Plane symmetry only, last choice
<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- x = y
- 2(70 + 60) + x + y = 360
<u>Work:</u>
- 2(130) + x + x = 360
- => 260 + 2x = 360
- => 2x = 360 - 260
- => 2x = 100
- => x = 50
Hence, <u>the value of x is 50°.</u>
Hoped this helped.
Answer:
OP = x, OQ = 2x => OP = OQ/2 = PQ = 10
=> OQ = 2 x PQ = 2 x 10 =20
