Question

Construct triangle ABC such that BC is equal to 3 cm and angle BCA is equal to 75 and a b + AC is equal to 8 cm​

Answer 1

Answer:

First take base BC 3cm

then take angle BCA 75 degrees and extend the line

now using your compass take 10cm and draw a arc of 10 cm on the extended line and name it as Angle D

now join angle B to Angle D

Now keep your compass on angle C and take more than the half of line DC and draw an arc

Now keep your compass on point D and repeat the same

Again draw arc on the other side by keeping your compass on Angle B and angle D

Now draw a line through the arcs drawn

and joint angle C to angle A as shown below

measure Line AB and AC and you should be getting 8 cm.
