Answer:
90,45,45
Step-by-step explanation:
it a system of equations
say that x y and z are each angles of the triangle
that means that they add up to 180 so x+y+z=180
the question says that two of the angles in the triangle are equal so we can just say that x=y
and it says that the two angles that are the same length have a sum that is equal to the third side of the triangle which basically is x+y=z
x+y+z=180
x+y=z
x=y
we start with the first two equations:
since x+y=z then we can substitute z in for x+y in the first equation
z+z=180
2z=180
z=90
and since x=y then
x+x=z
2x=90
x=45
y=45
z=90
hope that helps :)
