Question number 34 - 36 consists of 5 marks each.34. Construct a ABC in which BC = 7cm, ZB = 75° and AB + AC = 13cm.525'11​

Answer»

Step-by-step explanation:

Given,

to CONSTRUCT a ΔABC where

BC=7cm,∠B=75

∘

& AB+AC=13cm.

construction STEPS :-

(i) Draw a line segment BC = 7 cm as a base.

(ii) Now mark ∠B=75

∘

and extend it till x.

(iii) Now, by taking radius 13 cm draw an arc from 'B' on the line of angle just projected.

(iv) Now mark it as 'D', & join C to D.

(v) Draw ⊥

lar

bisectors for DC and mark them as P & Q.

(vi) Now extend a line from 'B' to the ⊥

lar

bisector that CUTS on C & D line.

(vii) Now mark that point as 'A'.

(viii) Thus, required ΔABC has been formed.

(ix) Now, try taking exactly 1/2 of the angle and mark an arc on B.

Conclusion :-

∴ The required ΔABC will BC = 7 cm,

∠B=45

∘

& AB + AC = 13 cm is
