Triangle A B C. Angle C is 80 degrees and angles B and A are y degrees. What is the value of y in the triangle? Angle y = °

50

Step-by-step explanation:

a triangle's sum of all angles is 180 degrees

so a+b+c=180

we know c=80

and a=b

so that'll be

2y+80=180

subtract 80 from each side

2y=100

divide by 2

y=50

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
