angle 2 = 114°

supplementary angles sum to 180° thus

5y + 16 + 10y + 14 = 180

15y + 30 = 180

subtract 30 from both sides

15y = 180 - 30 = 150

divide both sides by 15

y = \frac{150}{15} = 10

angle 1 = (5 × 10) + 16 = 50 + 16 = 66° and

angle 2 = (10 × 10) + 14 = 100 + 14 = 114°

5y+16+10y+14=180 became supplementary angles are always equal to 180.
To solve it..
1) 5y+16+10y+14=180 1) Given
2) 15y+30=180 2) Combine like terms
3) 15y=150. 3) Subtraction P.O.E
4) y= 10. 4) Division P.OE
5) 10(10)+14. 5) Substitution P.O.E
6) 100+14 6) Distribution
7) m<2=114

Yes, she will because 
E.X.:
<span>Divide the sales tax percentage by 100 (or simply move the decimal point two places to the left) to get the decimal equivalent of the rate. So if the tax rate was 7.375%, the decimal equivalent would be .07375.<span>Multiply the taxable price by the decimal equivalent of the rate. For example, if the taxable price was $50.00 and the rate was 7.375%, then the sales taxes would be $3.69 ($50 x .07375 = 3.6875 = $3.69 when rounded to the nearest cent). Hopes this helps if not I can explain it better.</span></span>

How many words is 2-3 pages double spaced?
seropon [69]
It would be tricky to determine the number of words since there could be different usage of margins, font sizes and font styles.

However, based on an study by an institution, a 2-3 pages essay contains approximately 750 words in general.

The statement is true if you're going to use Arial 12, double spacing with 1 inch margin on a word document.
