Total measure is 180

x is 2nd and y is 3rd angle
2nd is 4 times 3rd angle
x=4y

total is 180

20+x+y=180
x=4y
20+4y+y=180
20+5y=180
minus 20 both sides
5y=160
divide by 5
y=32

third angle is 32 degrees

Bob took 20 math test last year if he failed 6 of them what percent of the math test did he pass

kodGreya [7K]

6 out of 20=what percent?
6/20=x%

percent means parts out of 100
x%=x/100

6/20=x/100
time both sides by 100
30=x
answer is 30% passed

100-30=70
70% is answer
