Answer:
Sin A = 0.38462
Step-by-step explanation:
From the trigonometric function,
Sin A =
................... 1
So that, applying the Pythagoras theorem to determine the value of hypotenuse,
=
+ 
=
+ 
= 576 + 100
= 676
Hyp = 
= 26
The hypotenuse of the triangle is 26.
Thus, from equation 1;
Sin A = 
Sin A = 0.38462
There must be 23 students in Ms.Gardner's class because 23 - 30%=6.9 so 7
students are in her class are in the play because if you look at
Mr.Logan's class he has 23 students to and there are aslo 7 students in
his class are in the play so Mr. Logan's class is basically is holding
Ms.Gardner's place
