∠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 "≤"
