If a perpendicular bisector of PQ

is constructed, what is the result?

60 cm
7096

two segments, each 120 cm long
ans

two segments, each 90 cm long
.mp4

two segments, each 30 cm long

two segments, each 60 cm long

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

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2

y=-2x+1500

step-by-step explanation:

+1500

2 over one
