The measure of angle F is 130 degrees.A part of angle F measures 70 degrees.
What is the measure of the other part if the angle?

Answers

130 degrees is the total degrees of the angle,
So if part of that angle was 70 degrees with a missing part you can just subtract to find the missing angle.
(130-70=60)
The missing angle equals 60 degrees

i think its 60 because 130-70 = 60

Chelsea shows her work in finding the solution to 40x– 5 = 2+ 3(x– 3). Afterchecking her answer in the original equation, she found that it did not work. Where did she make a mistake?
a. step 1: she distributed incorrectly
b. step 2: She subtracted 3x incorrectly
c. Step 3: she’s simplified incorrectly
d. step four: she subtracted 5 instead of adding 5

Answers

Answer:

The mistake that Chelsea made was that she instead of adding 5 to both sides at step 4, she subtracted them. If she added the 5 instead of subtracting it, the answer she should've gotten was -2.

Answer:

Step 4: She subtracted 5 instead of adding 5.
