Answer:
Please provide an image of the triangle so that an answer can be provided.
270 I think but I’m not 100% sure
As is shown in the figure attached:
1. "A" and 76º are congruents, because they are Alternate Interior angles, so A=76º.
2. "D" and "x" are congruents,
because they are Alternate Interior angles, so x=38º.
3. "A", "B" and "C" form a the triangle ABC. Then, we remember sum of the interior angles of a triangle is 180º, so we have:
76º+38º+B=180º
B=180º-76º-38º
B=66º
4. By definition, an exterior angle of a triangle is equal to the sum of the opposite interior angles to it. So, we can calculate the exterior angle "y" of the triangle ABC, as follows:
The opposite angles are: 76º and 66ª. Then, we obtain:
y=76º+66º
y=142º
Therefore, the answer is: The value of y is 142º.
It would be 12 because if you divide 9 by 3/4 also known as .75 (by dividing 3 over 4) you get 9. In the picture is an example of what the dividend divisor and quotient are. Hope this helped! If not, you can ask me
The given expression is

49 is the square of 7 and 64 is the square of 8.
So we can write the given expression as
