Question

Q-3) Solve the following.
1) Find the circumference of the garden having radius 20 m.(x = 3.14)
2) The length of the sides forming a right angle of a triangle are 12 cm and
17 cm. Find the area of the triangle.
3) The measure of minor arc AXB is 112°, what is the measure of its
corresponding ajor arc AYB?
4) Expand (x - 2)2​

Answer 1

Answer:

XD

(x-2)2

Step-by-step explanation:

4) 2x-4, x= 4/2

x= 2

Answer 2

Step-by-step explanation:

1) Diameter of circle (d) = 20 cm. ∴ Circumference = dπ = 20 × 3.14 = 62.8 cm.

2) Area of triangle =1/2 × base × Height

=1/2 × 17 × 12

=17/6

$102cm ^{2}$

3) Consider that arc AXB is the minor arc and arc AYB is the corresponding major arc. It is known that the measure of major arc = 360

The measure of the corresponding minor arc. we Have, m (arc AXB) = 120°

=360 - 120 = 240

Hence the answer is 240°
