no because she turned it only 90 degrees not 180.
180 would be a mirror reflection
Answer:
3x−y=5;x+2y=4
x=2 and y=1
Step-by-step explanation:
Answer:
A. Right Triangle
D. Isosceles
Step-by-step explanation:
Well, since it has a square at the bottom of the triangle, it means it's a right triangle, because it has a 90 degree angle.
It is also an isosceles triangle, because two of the sides are of equal length.
Hope this helped!
:)
The total amount of degrees in a triangle is 180. All three angles should add up to 180˚
We know that 40+60 = 100
The next step is to do 180-100 to get the other angle.
180-100 = 80
So the measure of the third angle is 80˚
Hope this helps!
(Also if you want to do this in one equation, you would do 40+60+x = 180
40+60+x = 180
100+x = 180 (combine like terms)
x = 80 (Subtract 100 from both sides)
