A. find the value of a. B. Find the value of the marked angles.
Marat540 [252]

The marked angles are opposite angles, and as such they have the same measure. So, we have

6a+11 = 2a+83

Subtract 2a and 11 from both sides to get

4a = 72

Divide both sides by 4 to get

a = \dfrac{72}{4} = 18

Now that we know the value of a, we can compute the measure of the angles. We can also verify that the solution we found is correct by verifying that both expressions actually give the same result:

6a+11 = 6\cdot 18 + 11 = 119

2a+83 = 2\cdot 18 + 83 = 119

What is 75 2/5% in decimal
krok68 [10]

Answer:

.754

Step-by-step explanation:

Percentage is based off of 1 or 100% which is equal to 1. So 50% or half of both 100% and 1 would be translated as .5 and as the percentage becomes more accurate or lengthy you add to the decimal so 53% is .53 and 53.4% is .534
