∠A = 106.3°, ∠B = 20.6°, ∠C = 53.1°

Step-by-step explanation:

In a ΔABC, the sides opposite to the angle A is a, angle B is b, and angle C is c. a = 60 , b= 22, c = 50

We can find any one angle by cosine rule,

a² = b² + c² - 2 bc cos (A)

60² = 22² + 50² - 2(22)(50) cos A

3600 = 484 + 2500 - 2200 cos A

3600 = 2984 - 2200 cos A

3600 - 2984 = -2200 cos A

616 = -2200 cos A

cos A = 616/ -2200 = -0.28

A = cos⁻¹ (-0.28) = 106.3°

Now we can use sine rule to find angle B as,

sin A/ a = sin B / b

sin  106.3° / 60 = sin B / 22

sin B = 22 × sin  106.3° / 60

 B = sin⁻¹ (22 × sin  106.3° / 60 ) = 20.6°

As we know the sum of angles in a triangle is 180°.

∠A + ∠B + ∠C = 180°

106.3° + 20.6° + ∠C = 180°

126.9° + ∠C = 180°

∠C = 180° - 126.9° = 53.1°

Answer:

The correct inequality symbol to compare the two expressions 2.42√181.4 and √√16 is the "≤" symbol, which represents "less than or equal to."

Step-by-step explanation:

To understand why, let's evaluate the two expressions separately:

Expression 1: 2.42√181.4

This expression involves finding the square root of 181.4 and then multiplying it by 2.42. The result will be a specific number.

Expression 2: √√16

This expression involves taking the square root of 16, which is 4, and then taking the square root of 4, which is 2. The result will also be a specific number.

Now, we need to compare these two numbers. The inequality symbol "≤" means "less than or equal to." In this case, it implies that the value of Expression 1 is either less than or equal to the value of Expression 2.

Since we have evaluated the expressions and know that Expression 1 is a specific number and Expression 2 is also a specific number, we can compare them using the "≤" symbol. This means that Expression 1 is less than or equal to Expression 2. Therefore, the correct inequality symbol to compare the two expressions is "≤"

hope it helped !~
