First we can take the ratio 2:3 as 2y and 3y , It is a linear pair so angle a + angle b=180° 2y+3y=180° 5y=180° y=180°/5 y= 36° Hence y=36°, 2y=2(36)= 72° 3y=3(36)=108° Hence the angles are 72°and 108°.

Sia ? 4 years, 6 months ago

(a−2b−3c)²
According to the equation ,
(a+b+c)²= a²+ b²+ c²+ 2ab + 2bc + 2ca
So we get,
Using the formula we can it write it as
(a−2b−3c)²= a²+(−2b)²+(−3c)²+2a(−2b)+(2(−2b)(−3c)+2(−3c)a
On further calculation we get,
(a−2b−3c)²= a²+ 4b²+ 9c²− 4ab + 12bc − 6ac
