At a high school, the ratio of boys to girls is 2 to 3. If there are 580 total students at the school, how many boys attend?

232

Step-by-step explanation:

You can make a modal of this:

The blue squares are all the same amount. Therefore, the boys have 2 squares and the girls have 3. You can add these up and get 5 squares in total. Since all these squares have the same value, each of these squares are 580/5=116. Then you multiply this by 2 because there are two boxes for boys, and get  232 as your final answer

Also if you are confused on how I know there are only 5 boxes, there are only boys and girls in the school so the amount of boys + the amount of girls= the total amount of people in the school.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
