Find the value of R that will make the equation sin 62° = cos R true when 0° < R < 90°.
1 answer:
The value of R is 28° (Degrees), if the equation sin 62° = cos R true when 0° < R < 60°.
Step-by-step explanation:
The given is,
sin 62° = cos R
0° < R < 90°
Step:1
Form the given equation,
sin 62° = cos R.......................(1)
Where,
sin 62° = 0.88295
From the value of sin 62, equation (1) becomes
sin 62° = cos R
0.88295 = cos R
R = 0.88295
R = 27.9997
≅ 28°
R = 28°
Step:2
Check for solution,
From equation 1,
sin 62° = cos R
Substitute R = 28°,
sin 62° = cos 28°
0.88295 = 0.88295
Result:
The value of R is 28° (Degrees), if the equation sin 62° = cos R true when 0° < R < 60°.

Answer:
Step-by-step explanation:
From the question we are told that:
Table for price per Kg
Watermelon Rs 18.50
Cherry Rs 72
Grapes Rs 120.60
Apples Rs 78.40
Karan Bought:
412 kg watermelon
1 kg 200g cherries
250 g grapes
134 kg apples
Generally the equation for Total Price of Fruits Bought is mathematically given by
\sum (Price Rs* Weight kg )
Therefore the Amount of Money he gets back is
Therefore
He owes the shop keeper 2.74 million Rs
