Which set of side measurements could represent a right triangle? A. 200 cm, 300 cm, 500 cm

B. 300 cm, 400 cm, 500 cm

C. 400 cm, 300 cm, 500 cm

D. 600 cm, 700 cm, 800 cm

c I do believe good luck with the answer

B and c

Step-by-step explanation:

B. 300 cm, 400 cm, 500 cm

C. also.

Here

500² = 300 ² + 400²

250000 = 250000

Hope it helps :)❤

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
