Answer:
No
Step-by-step explanation:
It would not form a right triangle because if you square 20, 30, 40, and add 20^2 and 30^2 it would become 1,300, but 40^2 is 1,600 which does not make it a right triangle according to the Pythagorean Theorem.
Yes because if you add forty and thirty that equals seventy plus twenty is 90 which is a right angle
36 times 8 = 288
i dont know, sorry.
B. 38.5
Not 100% sure, but
41+36=77
77/2=

3*4=12
12-2=10
10*2=20
20+15=35
35*2=70
