Answer 1

Answer:

In a 3.ABC, 2C=32B=2(ZA+ZB). Find the three angles

the vertices of the triangle formed by these lines and the y axi

(iv) (a - b)x + (a+by=

(a+b)(x + y)=+b

number of stud

7. Solve the following pair of linear equations:

+gy = P-9

qr-py =P +9

(ii) ax + by = 0

bx + ay = 1+c

%px +

X Y = 0

line

pa

ax + by = a² + b2

(v) 152x-378y=- 74

-378r+ 152y=-604

ABCD is a cyclic quadrilateral (see Fig. 3.7).

Find the angles of the cyclic quadrilateral.
