The correct answer is 1/3 if you follow order of operations.
Answer:
The cosine of angle C is 5/13, or approximately 0.38.
Step-by-step explanation:
To solve this problem, we must remember what the cosine of an angle represents. The cosine of an angle is equal to the ratio of the adjacent side divided by the hypotenuse.
From the diagram, we can determine that the adjacent side length is 10 and the hypotenuse is 26.
Therefore, the cosine of angle C is:
10/26 = 5/13 (simplified)

A slope line, in physics is decided amount of. Speed
The circumference of the circle E is :
C = 2 r π
C = 2 * 40 π = 80 π cm.
Also 324° / 360° = 0.9
m Arc (ABC ) = 0.9 * 80 π = 72 π cm
There is also formula for calculating the measure of an arc:
m Arc = r π α / 180°
m Arc = 40 π * 324 / 180 = 40π * 1.8 = 72 π
Now we have to find the exact length ( π ≈ 3.14 )
m Arc ( ABC ) = 72 * 3.14 = 226.08 cm
Answer: There are 450 million mobile users in India last year.
Step-by-step explanation:
Since we have given that
Number of mobile users today = 540 million
Every year mobile users in India have gone up by 20% in a year.
Let the number of mobile users in India last year be x
So, According to question, we have,
Hence, there are 450 million mobile users in India last year.
