Answer: 5.4

--------------------------------------

Explanation:

Angle D = 43 is the given reference angle
side FE = 5 is the side opposite the reference angle (since its the leg furthest away from angle D)

We want to find side DE which is the other leg. This is the adjacent side with angle D as the reference angle

Use the tangent rule

tan(angle) = opposite/adjacent
tan(D) = FE/DE
tan(43) = 5/DE
DE*tan(43) = 5
DE = 5/tan(43)
DE = 5.36184355 <<-- use a calculator here; this is approximate
DE = 5.4 <<-- round to the nearest tenth

That's why 5.4 is the answer

What is the nth term for the sequence 5, 11, 19 29, 41,....
Mila [183]
The answer would be 55 because the sequence it`s going by is adding 2 to the number you`re adding up by. So for example, 5+6 =11, 11+8=19, 19+10= 29. and 29+12 == 41, so the next one would be 41+14=55. Does that makes sense?
