Question

. Construct ∆ABC in which BC = 7.8cm, ∠B = 45º and ∠C = 60º, construct angle

bisectors of ∠B and ∠C and intersect them at point O. Measure ∠BOC.​

Answer 1

Answer:

Construct a triangle AbC, in which 20- 60, E45' and AB + DC

+ CA = 11 cm

Given 48 = 60.4C 45 and AB - BC ca CA- 11 em

Let's construct AAC

Steps of Construction:

1. Draw A line segment XY equal to AB + AC + BE= 11 tm.

Step-by-step explanation:

2. Make angle equal to 2.B=60" from point X tet the angle be e LXY

3. Main angle equal to 20 5* from print Y Let the angle be 2 MYX

4. Bisect LXY and 2 MYX.

Let these bisectors intersect at a point A.

5. Make perpendicular bisector of AX

Let it intersect XY at print

6. Male perpendicular bisector of AY

tet it intersect XY at paint
