Answer:
x= 15
y= 5
Step-by-step explanation:
it is a reflective opposite side exterior angle or line you are seeing.
The angle on the other side is a vertical angle meaning it is the same. Which leads to show that the measurements are the same as well.
Answer:
36
Step-by-step explanation:
positive version
I'll Give You Some Hints:
Let's Look at C.
In C, the triangle is translated 2 units to the right. Which means that it cannot be a reflection.
Let's Look at B.
In B there is a sideways triangle. That means it's a Rotation. Which means it's not Reflected.
Lastly, Let's Look at A.
To get from the original triangle to the triangle in A, you have to reflect twice. Once along a vertical line, and then along a horizontal line.

Answer:
5
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 10^2 = (5 sqrt(5))^2
a^2 +100 = 25(5)
a^2 +100 = 125
a^2 = 125-100
a^2 = 25
Taking the square root of each side
sqrt(a^2) = sqrt(25)
a = 5
AC would be equivalent to 4. I know that the triangle is a 90, 45, 45 triangle which means 2 of the angles AND sides are equivalent to each other. Since angle B is 45 degrees angle C has to be 45 degrees. Same goes for the sides. Since AB=4, AC=4. It wouldn't be BC bc that's the hypotenuse or the longest part of the triangle. AC wouldn't be equal to 2 since it won't follow the rule of a 90, 45, 45 triangle. :|
