Question

please tell me the answer ​

Answer 1

Construct ∆ABC,given m angle B=30° and AB=5.8°.

given

,

and AB = 5.8 cm :

1. Draw the line AB=5.8 cm

2. At A making an angle 60 degrees with AB draw a line AX

3. At B making an angle 30 degrees with AB draw a line BY

4. The lines AX and BY intersect at C ( in case the drawn line AX or BY is small extend it to intersect each other)

ABC is the requires triangle

Answer 2

Answer 36

• Draw a line AB= 5.8 cm
• From A make an angle 60 with the help of compas
• From B make an angle 30 with the help of compas
• Name the intersection point C
• There for ABC is the required ABC

1. Answer37

• Circumference of circle = 2πr
• 154=2 X 22/7 X R
• 154 X 7/44 = R
• R = 49/2 And 24.5
• There for Radius = 49/2 and 24.5
• Area of circle = π R(square)
• area = 22/7 X49/2 X 49/2
• Area = 1,886.5
