from the top of a vertical cliff 50 m high, the angle of depression of an object that is level with the base of the cliff is 70°. how far is the object from the base of the cliff?

18.2

Step-by-step explanation:

tan 70 = 50/x

x = 50/ tan 70

a. 3/4 ÷ 1/8 = 6

step-by-step explanation:

in the question, the number line represents 3/4 divided into 6 equal units. each arrow represents a unit and there are a total of six arrows.

the size of each unit is 1/8 as shown.

showing that 1/8 divides 3/4 into 6 divisions:

3/4 ÷ 1/8

= 3/4 x 8/1

= 3/1 x 8/4

= 3 x 2

= 6

hence, the number line represents six divisions given by 3/4 ÷ 1/8.
