As far as I can tell is a combination, since the positions are unique,
Answer:
x = 16°
Step-by-step explanation:
The three internal angles of the triangle are:
180° - 91° = 89° (angles in a straight line)
180° - 105° = 75° (angles on a straight line)
x = x (vertical angles are congruent)
x + 89 + 75 = 180 (sum of interior angles of a ∆)
x + 164 = 180
x = 180 - 164 (subtraction property of equality)
x = 16°
7*(60+3)=7*60+7*3= 420+21=441
The answer is D) All the steps and the answer are correct. :)
You can just solve using the steps to see if they are right. For example, is -1x17=-17? Yes.
Answer: 15 months
Step-by-step explanation:
Her balance after paying the registration fee is $300. Then we need to divide this remaining money into as many chunks (months )of $20. So we do 300/20 = 15 months
