Find the product 7 x 300 = hundreds

7 x 300 = 2,100 hope i helped and there are 21 hundreds in 2,100

Use basic facts like 7x3= 21 Then add the zero which are three so you end up with 2,100 hope i helped

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
