Answer 1

H E L L O - M A T E

Step-by-step explanation:

Let AB be the pole and BC be its shadow.

Given that AB/BC = 1/√3

Let ACB be the angle of elevation.

In triangle ABC,

X is equal to theta

tan x = AB/BC

tan x = 1/√3

tan x = tan 30

X = 30

Answer 2

1. Let the ratio part will be x

1:1

1x+1x=40 degree

2x=40

x=40/2=20

20×1=20

20×1=20

2.1:1

1x+1x=60 degree

2x=60

x=60/2=30

30×1=30

30×1=30

3.1:1

1x+1x=45 degree

2x=45

x=45/2=22.1

22.1×1=22.1

22.1×1=22.1

4.1:1

1x+1x=30 degree

2x=30

x=30/2=15

15×1=15

15×1=15
