In APQR, find the measure of Z.P.

egoroff_w [7]

Step-by-step explanation:

multiple possibilities.

e.g.

we could use Pythagoras to get QR, and then use the law of sine to get angle P.

or we can use the law of sine to get angle R, and then use the rule that the sum of all angles in a triangle is always 180° to get angle P.

I propose the second option :

the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

with a, b, c being the sides always opposite of their associated angles.

33.8/sin(R) = 57.6/sin(90) = 57.6

sin(R) = 33.8/57.6 = 0.586805555...

R = 35.93064691...°

180 = 90 + 35.93064691... + P

P = 54.06935309...°

Angle c is inscribed in circle O. AB is a diameter of circle O. what is the radius of circle.

Llana [10]

Answer:

The value of radius is 7.5 units

Step-by-step explanation:

Given that a line that pass through the origin and form a triangle is a right-angle triangle. So in order to find the diameter/hypotenuse, you have to use Pythogaras Theorem :

${c}^{2} = {a}^{2} + {b}^{2}$

Let a = 12 units,

Let b = 9 units,

Let c = hypo.,

${hypo.}^{2} = {12}^{2} + {9}^{2}$

${hypo.}^{2} = 225$

$hypo. = \sqrt{225}$

$hypo. = 15 \: \: units$

We have found out that the hypotenuse of the triangle is the diameter of circle. So in order to find radius, you have to divide it by 2 :

$radius = diameter \div 2$

$radius = 15 \div 2$

$radius = 7.5 \: \: units$

What fractions are in between -1/3 any -2/3

UNO [17]

To find a fraction between two fractions, all we need to do is make the sum of the numerators be the new numerator, and the sum of the denominators be the new denominator.(x) So, for example, a fraction between 7/13 and 6/11 is (7 + 6)/(13+ 11) =13/24.(x)

7/13 = .5384615(x)

6/11 = .545454(x)

13/24 = .541666�
