<h2>
Rate at which area is increasing is 1.08 m²/s.</h2>
Step-by-step explanation:
Area of triangle is with side a and b and angle C between them is given by
A = 0.5 ab SinC
Here we need to find how area changes with a and b fixed and C is changing,

We have
a = 8 m
b = 9 m

Substituting

Rate at which area is increasing is 1.08 m²/s.
Answer:
Option b
Step-by-step explanation:
To solve this problem use the law of the sines.
We have 2 angles of the triangle and one of the sides.

The law of the sines is:

Then:


5 students like cheesecake because if there is 20 students in all and 15 like chocolate and the rest like cheesecake you do 20-15=5
If 5 students like cheesecake out of 20 it would be 5/20 20*5=100 just multiply by 5 5*5=25%
25% of students like cheesecake
63/240 seats or 21/80
The greatest common denominator is 3, so you would divide both by 3.
