What is the value of a 3 - b 2 for a = 3 and b = 1/2

Hello!

You put the values in for a and b

a^3 - b^2

3^3 - 2^2

27 - 4 = 23

The answer is 23

Hope this helps!

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

Igot 108 hope that’s right !
