Answer:
Step-by-step explanation:
If two angles and the included side of one triangle are equal to two angles and includedside of another triangle, then the triangles are congruent. This is because the angles will always intersect at the same point since the angles are the same and their base is a controlled variable since they are the same.
Answer:
180-77
Step-by-step explanation:
adjacent angles are supp
To find the variable x, set the two outside equations equal to each other because all sides are equal
x+13=3x+3
13=2x+3
10=2x
x=5
then to find h, you set the equation equal to 90 because that's how many degrees it is
2h-45=90
2h=135
h=67.5
