Question

1. In a triangle, the lengths of two larger sides are 10 cm
and 9 cm. If the angles of the triangle are in AP, then
the length of the third side is



​

Answer 1

Answer:

8

Step-by-step explanation:

t1 - 10

t2 - 9

d=t2-t1=9-10=-1

so,

d=-1

then,

the third term is...

t3=t2+d

t3=9+(-1)

t3=8
