The area of rectangle ABCD is 15 square units.
Answer:
Correct answer is option A. T
Step-by-step explanation:
Given that
In a , RS = 7, RT = 10, and ST = 8.
To find:
Smallest angle = ?
Solution:
We can use cosine rule here to find the angle.
Formula for cosine rule:
Where
a is the side opposite to
b is the side opposite to
c is the side opposite to
Using the cosine rule:
Now, let us use Sine rule to find other angles:
Smallest angle is
