Find degree measures of marked angles in fig 5.47​

50+P=125 exterior angle of the triangle is equal to the sum of two opposite interior angle

P=125-50=75°

q+125=180 linear pair

q=180-125=55°

r=q=55° vertically opposite angle

s+85=125 exterior angle of the triangle is equal to the sum of two opposite interior angle

s=125-85=40°

s+t=180 linear pair

t=180-40=140°

u=s=40° vertically opposite angle

w=65° vertically opposite angle

v+u+w=180 sum of interior angle of the triangle is 180

v+40+65=180

v=180-105=75°

x+65=180 linear pair

x=180-65=115°

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
