The sun subtend an angle at 35degree from the centre of the earth whose distant from the

centre of the earth is 382,100km. find the diameter of the sun

(a) 600km (b) 650km (c) 648.6km (d) 648km

answer: i believe its b. if you sound out the sentences that sounds wrong.

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
