we know, that the angle formed by an arc at the center of the circle is two times the angle formed by same arc on any point on the circumference,

So,

=》

$angle \: 1 = 2 \times angle \: 2$

hence, correct answer is B.

Identify sinJ as a fraction and as a decimal rounded to the nearest hundredth.

KiRa [710]

In the given right triangle, the trigonometric ratio, sin J has a fractional value of 5/13 and a decimal value of 0.39.

In trigonometry, for a right triangle, the sine (sin) of any angle θ is given as the ratio of its opposite side to the hypotenuse of the triangle, that is, sin θ = (opposite side)/(hypotenuse).

In the question, we are asked to find the trigonometric ratio, sin J, for the given right triangle JKL.

The side opposite to angle J is KL, which has a value of 3 units.

The hypotenuse of the given right triangle is JK, which has a value of 7.8 units.

Thus, sin J can be calculated as:

sin J = KL/JK = 3/7.8 = 5/13 = 0.39.

Thus, in the given right triangle, the trigonometric ratio, sin J has a fractional value of 5/13 and a decimal value of 0.39.

Pythagorean theorem: find the perimeter

denis-greek [22]

The answer is 5
Explanation:
We need to use the Pythagorean,
a^2 + b^2 = c^2
Where c is the hypotenuse
We can fill in spots now 12^2 + b^2 = 13^2
And then we solve 144 + b^2 = 169
Next we get b^2 alone
169-144=25
So we get b^2=25
For the final step you have to find the square root of 25 to get b alone which is 5

Javon plays on the Bunker Hill basketball team and Coach Jones sets a goal for him to average a minimum of 18 points per game in

Misha Larkins [42]

If he does average exactly 18 points per game in the first 6 games, then his TOTAL points in those 6 games will be (6 x 18) = 108 points.

In his first 5 games, he has (20 + 17 + 14 + 18 + 19) = 88 points so far.

In order to total 108 for 6 games, he has to score (108 - 88) = 20 points in the 6th game. If he scores more than that, then his average for the 6 games will be more than 18 points per game.

In order to meet the goal that Coach Jones has set for him, Javon must score 20 points or more in the next game. S ≥ 20 .

This might scare Javon ... he has to equal or beat his best performance of the last 5 games.
