Answer:
What is part 1?
Step-by-step explanation:
Answer:
108 deg. These are vertically opposite angles.
Step-by-step explanation:
Corresponding angles are for example EFB and ABC.
Alternate angles are for example EFB and FBD.
All three angle options describe equal angles.
Answer:
67
Step-by-step explanation:
do the math. or just use a calculator because there is no sign between the -15 and the -4 so you multiply. it turns positive the add the 7. easy peezy
Answer:
See below
Step-by-step explanation:
15)
In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is .
The angle of the other triangle plus the angle of the right-angle triangle is equal to 90º, therefore they are complementary angles.
So,
To find ?, we have
16)
The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is
Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have
