Tips with decimals....
Our decimal system gives us the flexibility to write numbers as large or
small as we like. The key to the decimal system is the decimal point. Anything
on the left of the decimal point represents a whole number, anything on the
right of the decimal represents less than one (similar to a fraction). Going
from left to right, the value of each place on the right of the decimal point is
1/10 the value of the place on the left. Good luck!
Answer:
m∠A = 106°
Step-by-step explanation:
All three sides of the triangle are given in the question.
To find the measure of included angle A between two sides we will apply cosine formula,
BC²= AB² + AC² - 2(AB)(AC)cosA
(13)² = (10)² + (6)² - 2(10)(6)cosA
169 = 100 + 36 - 120cosA
cosA = 
cosA = -0.275
A = 
A = 105.96°
A ≈ 106°
Therefore, m∠A = 106° will be the answer.
She would save 54.45 because addding them up individually before the plan would cost 184.49 and to find the difference all you have to do is subtract 184.49-129.99 and that would tell you how much she saved
