Answer:
B
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ FES is an exterior angle of the triangle , then
57° + ∠ F = 142° ( subtract 57° from both sides )
∠ F = 85°
A) multiply them
When you have a power of a power you multiply the powers together
16 is 80% of 20. 80% is the same as .8. .8×20 is 16.
There least common factor would be 5 since they are all divisible by 5.
If there are 196 refrigerators produced daily, that means that 8 are produced in an hour. subtract 8 and 3 and you get 5 refrigerators that are not defects. now multiply 5 by 24, about 120 refrigerators out of the 196 are not defects.
