Question

boojho went to a park. he went up the slide to play. the angle of elevation of the side is 30°. but the base from which the angle of elevation is measured is 5 cm above the ground level and the distance from the staircase is 10 cm. (use √3=1.732)​

Answer 1

1. yes
2. 30°
3. 10.773m approx
4. 11.547m approx

Answer 2

Answer:

1.Increase

2.60°

3.10.77

4.14.69

Step-by-step explanation:

2. Since it is a right angled triangle and total sum being 180, angle of depression=180-(30+90)= 180-120=60

3.(since there is no angle theeta i will be using @

Tan @= Opposite side/Adjacent side

Tan 30=x/10

1/√3=x/10

x=10/√3=5.77

Total stair = 5+5.77=10.77

4.According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle

so√( 10.77^2+10^2)=14.69
