Radian to degree conversion.
4(pi)/3 degrees= 4(pi)/3 × 180/pi radians
As pi radians= 180 degrees
Dividing both sides by pi :
pi / pi radian= 180/pi degrees
1 radian=180/pi degrees
4 × pi /3 × 180/ pi
pi and pi gets cancelled.
180/3= 60
4× 60
=240 degrees

<span>Triangle PQR is a right triangle. First we have to find the length of each side of the triangle. This can be done using the points provided, along with the Pythagorean theorem, which is a^2+b^2=c^2.
PR^2 = (7- -2)^2+(3-5)^2 = 85 => PR = sqrt(85)
QR^2 = (7- -1)^2+(3-1)^2 = 68 => QR = sqrt(68)
QP^2 = (1-5)^2+(-1 - -2)^2 =17 => QP = sqrt(17)
Now that we have the sides of the triangle, we can put them into the Pythagorean theorem again to see that it works out:
(Sqrt(17))^2 + (sqrt(68))^2 = (sqrt(85))^2
17 + 68 = 85
85 = 85
Since the Pythagorean theorem works for right triangles, the triangle is indeed a right triangle.</span>
Answer:
7/8
Step-by-step explanation:
7/8 because he completed 4/8 (half) before he finished dinner. 4+2=6. So/ it should be 7/8.
