Answer:
They are congruent by the AAS theorem!
Step-by-step explanation:
Sides EF and HJ are congruent, angles E and J are congruent and angles EGF and HGJ are congruent because they are vertical angles. Therefore, the triangles are congruent by the AAS theorem!
Hope this helps you :)
Answer:
the answer is 55
Step-by-step explanation:
all angles have to equal up to 180.
55+30=85
85+40=125
180-125=55
The angles 90, 40, and 50 are possible for a triangle.
The angles 82, 38, and 60 are possible for a triangle.
And the angles 59, 31, and 90 are possible for a triangle.
This is because the sum of all three angles of a triangle must be 180 degrees.
Answer: 23.2
Step-by-step explanation:
Answer:
Just 1
Explaination:
If one line has a positive slope and the other a negative slope, they are bound to intercept eventually, so that's why there can't be zero solutions. Two lines can't intercept each other twice, and if they have opposite slopes they can't have infinite solutions.
