I would say acute If I am wrong sorry
No, because he can only type 40 words a minute
To calculate the area of a rectangle you multiply the length of the the sides, on 38) the sides are 4 and (3x-2) so to find the area do 4 x (3x-2) = 12x-8
To find the area of a right angled triangle you multiply the two sides and then divide by two, so for 39) and 40) follow this method but divide by two after as they’re triangles to find the area for these
I think yes. If not my bad.
