Answer:
B. 45
Step-by-step explanation:
To solve for angle A, we need to find the value of x. First, we need to find the interior angles of the triangle. We already know 2 of them, x+57 and 63+x but we need the third one. We can do that by subtracting 96 from 180 which is 84.
So now that we have the three interior angles of the triangle, we can make an equation. We already know that the sum of interior angles of a triangle is 180.
84+(x+57)+(63+x) = 180
Simplifying, we get:
204+2x=180
2x = -24
x=-12
Plugging x = -12 into x+57 gives 45 degrees. So, the answer is B.
let's recall that an isosceles triangle has two twin sides.

Answer:12
Step-by-step explanation:
Given
Balthazar,Rudy,Jebediah and Ezekiel in a single-File line to pull sleigh
Jebediah and Ezekiel Stay together
i.e. we need to arrange three person considering Ezekiel and jebediah as Single person
therefore 3 person can be arrange in 3! ways =6
and also Ezekiel and Jebediah can be arranged in 2 ways
Therefore a total of
ways are possible
Answer:
80v
Step-by-step explanation:
Multiply the numbers: 12 * 4 = 48
=48v + 8 * 4v
Multiply the numbers: 8 * 4 = 32
=48v + 32v
Add similar elements: 48v + 32v = 80v
Answer: 80v
