Answer: 31.43 meters
Step-by-step explanation:
First find the circumference of the circle.
= π * diameter
= 22/7 * 80
= 251.43 meters
If there are 8 points equally spaced, the distance between the points is:
= 251.43 / 8
= 31.43 meters
In this question, it is given that
The measure of angle Q is 96 degrees. The length of side P Q is 30 feet. The length of side R P is 54 feet.
And to find the measurement of angle R, we have to use sine law, which is
Substituting the given values,we will get
Correct option is the second option .
Answer:
5
Step-by-step explanation:
3×9×X=135
27×X=135 divide 27 from both sides
missing side is 5
Answer:
x = -2/3; x = 5/2.
Step-by-step explanation:
6x 2 - 11x - 10 = 0
Use the 'ac' method:
6 * -10 = -60. We need 2 numbers whose product is -60 and whose sum is -11.
That would be -15 and +4. So we write:
6x^2 - 15x + 4x - 10 = 0 Factor by grouping:
3x(2x - 5) + 2(2x - 5) = 0
(3x + 2)(2x - 5) = 0
x = -2/3; x = 5/2.
