Question

Construct triangle BOW in which angle B = 135°, BO=7.7cm and angle W=30°

Answer 1

Steps of construction :-

1. Draw a line BO.
2. Construct angle B and W using protractor.
3. Now, join the lines.
4. hence the triangle BOW is obtained.

Answer 2

construction of a triangle with two angles and one side

Step-by-step explanation:

(1) Draw the line segment BO  =  7.7 cm.

(2) Using protractor, at B, draw a ray BP making an angle of 135° with BO.

(3)Using protractor, at O, draw another ray OQ making an angle of 30° with BO

(4) The rays BP and OQ intersect at W.

(5) Using the property, "Sum of the three angles of any triangle is 180°",

we can find the third angle which is 0°.

$\angle B + \angle W + \angle O = 180$

135+ 30 + O = 180

$\angle O = 180 - 165$

$\angle O = 15$°
