Answer:
∠A = 45°
Step-by-step explanation:
It is given that,
sin A = sin B
∠C is a right angle.
If sin A = sin B, it means
sin 45 = sin 45 =
It means that angle A and angle B is 45 degrees.
Answer:
=4sqrt(10)
Step-by-step explanation:
The geometric mean of two numbers is sqrt(a*b) where a and b are the two numbers
geometric mean = sqrt(8*20)
=sqrt(160)
= sqrt(16*10)
We know that sqrt(ab) = sqrt(a) sqrt(b)
=sqrt(16) sqrt(10)
=4sqrt(10)
