Answer:
CBA
Step-by-step explanation:
B is the middle n angles should be btn two lines ie AB and BC. so they had a common point B hence the joining occured at B
Answer:
2 1/6
Step-by-step explanation:
How we calculate this is make the two fractions denominators the same so we can make them both 6.
for the 3 we times it by 2 and 2 by 3.
so our 2 fractions are now 2 4/6 and 3/6 Now
so if we take away 3 of 4 we get 1 so 2 and 4/6 is now 2 and 1/6
Meaning the 2 1/6 is what she has left so if she gives that all to her brother he gets that and there's your answer.
Hope it helps have a great afternoon:)

Answer:</h2>
x = 65° and y = 77.5°.
<h2>
Step-by-step explanation:</h2>
The triangle with the 50 degree angle and x, is an isosceles triangle. That means that the other unlabeled angle is also equal to x degrees.
x + x + 50 = 180
2x + 50 = 180
2x = 130
x = 65°.
Since x = 65 degrees, and the two angles make a 90 degree angle, the other unlabeled angle will be 90 - 65 = 25 degrees.
Since the other triangle is also isosceles, that triangle has two angles that measure y degrees and one angle measuring 25 degrees.
y + y + 25 = 180
2y + 25 = 180
2y = 155
y = 77.5°.
