Question

Plz ans the ques very fast Q3

Answer 1

given,

2A=3B, 5B=2C

A=3B/2

C=5B/2

3B/2+B+5B/2=180 (SUM OF ANGLES IN A TRIANGLE=180)

(3B+2B+5B)/2=180

10B/2=180

5B=180

B=36

Answer 2

The triangle formed will be equilateral triangle.

Let a triangle ABC with angles A,B,C

now A = (B+C)/2

AS B=C. (Given)

Therefore A= 2B/2

A = B
And. A=B=C

Therefore all the three angles of a triangle are equal.
Hence it is an equilateral triangle.
