The tagnet of the standard angles 0°, 30°,45°,60°and 90°​

Tan 0°= 0

tan 30°=√3/3

tan 45°=√(2/4) = 1/√2 = √2/2

tan 60°= √3

tan 90°= not defined

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
