Answer:
sin 0 = 24/25
cos 0 = 7/25
tan 0 = 24/7
Step-by-step explanation:
hey there!
sine = opposite divided by hypotenuse
the opposite of angle 0 is 24 and the hypotenuse is 25 so sin 0 = 24/25
cosine = adjacent divided by hypotenuse
the adjacent of 0 is 7 and the hypotenuse is 25 so cos 0 = 7/25
Tangent.= opposite divided by adjacent
the opposite of 0 is 24 and the hypotenuse is 7 so tan 0 = 24/7
Answer:
86 cm²
Step-by-step explanation:
<u>1) Calculate the area of the square</u>
Therefore, the area of the square is 400 cm².
<u>2) Calculate the area of the circle</u>
we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.
Therefore, the area of the circle is 314 cm².
<u>3) Subtract the area of the circle from the area of the square</u>
Therefore, the area of the shaded region is 86 cm².
I hope this helps!

The average score of all the students in both classes is 84.
<h3>How to calculate the average?</h3>
The class with 30 students had an average score of 80 on a test. The total score will be:
= 30 × 80
= 2400
A class with 20 students had an average score of 90 on the same test. The total score will be:
= 20 × 90
= 1800
Total scores = 2400 + 1800 = 4200
Number of students = 20 + 30 = 50
The average score will be:
= Total score / Total students
= 4200 / 50
= 84
