III. Identifica la propiedad en cada uno de los enuciado. 1) (x + 3) +5 = x +(3+5) 2.) 6 (x + 7) = 6 (X) + 6(7) 3.) 5.y = y. 5 4.) 6 = 1 5) 9+ 0 = 9 6) 65 +- 65= 0 7) 23. 1 = 23​

answer: finding the extract measurements and knowing the points

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

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

alaska, florida, nevada, south dakota, texas, washington and wyoming, tenessee and new hampshire.
