Only answer if yk how to do this

No

Step-by-step explanation:

Similar triangles must have the exact same angles

All angles must add to a total of 180° so to find x you can do 85°+64°=149° this means that 149°+x°=180° to find that you can do 180°-149° which equals 31°.

Then you do the same for the second triangle

1. 26°+85°=111°

2. 180°-111°=69°

because 69 and 31 aren't the same number these triangles aren't similar

similar triangles must have all the same angle amounts.

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
