∠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:
26ft/minute
Step-by-step explanation:
The question asks to calculate the rate at with a scuba diver is descending.
Firstly, we should know that the rate at which the scuba diver is descending is calculated as the total amount of distance descended, divided by the total amount of time taken.
The total amount of distance descended is 52ft + 130ft = 182ft
The total amount of time taken is 5 + 2= 7 minutes
The rate of descending is thus 182ft/7min = 26ft/minute
