Question 2.1 :

By Angle sum property we can find it .

\alpha + \beta + A = 180

 90 + 67.22 + A = 180

 A = 180 - 157.22

 A = 22.78

Correct option is ( A ) .

Question 2.2 :

He can find it by using some basic mathematical principals .

Given :

AB + BC = 34 m

AB = 34 m - 10 m = 24 m

AF = 9 m

BC = 7m

To find :

Length of pond or FG .

Solution :

By Pythagorean theorem .

AB² + BC² = AC²

(24)² + (10)² = AC²

576 + 100 = AC²

 \sqrt{676} = AC

 \bold{\boxed{26 m = AC}}

AC = AF + FG + GC

26 m = 9m + FG + 7m

FG = 26 m - 16 m

FG = 10 m

Length of pond is 10 m

Question 2.3 :

AC = 26 m

Same as in above question by Pythagorean theorem we have found it .

Question 2.4 :

We have found it in question 2.2 .

It is 10 m .
