Answer:
D)
Step-by-step explanation:
Answer:
1. x = 20
2. x = 45
Step-by-step explanation:
First Picture:
Because of vertical angles theorem, ECD is congruent to ACB making ACH 2x
Since a triangle adds up to 180 we can use the equation 2x + 2x + 100 = 180
From this, you will get x = 20
Second Picture:
Because we know that the lines are parallel you can use alternate interior angles theorem and make RST x too
Like the other problem, we can use an equation
In this case it is x + 2x + x = 180
You should get x = 45
800+4000+194
800+4000=4800
4800+194=4994
answer:4994
