hat is the area of a sector with a central angle of 4π5 radians and a radius of 11 cm? Use 3.14 for π and round your final answe

dusya [7]

4/5 PI radians = 144 degrees
sector area = central angle / 360 * PI * radius^2
sector area = 144 / 360 * PI * 11^2
sector area = 152.0530844337 square centimeters
sector area = 152.05 square centimeters

Which pair of angle measures satisfy the condition sin J = cos K? A. 15°, 40° B. 45°, 90° C. 60°, 30° D. 80°, 100° E. 70°, 110°

vaieri [72.5K]

Sin J = cos K
sin J = cos (90 - J)
K = 90 - J

sin 60 = cos (90 - 60) = cos 30

Therefore, 60°, 30° satisfy the condition sin J = cos K.

Answer:

90°

Step-by-step explanation:

$(\pi /2) * 180 = 90$

Whenever you are required to transfer from Radians to Degrees, simply multiply the Numerator by 180° (180). Treat the $\pi$ as a variable such as x and y, and divide by the numerator.
