Answer:
Obtuse
Step-by-step explanation:
The pythagorean theorem: a^2+b^2=c^2
Right triangles: a^2+b^2=c^2
Acute triangles: a^2+b^2>c^2
Obtuse triangles: a^2+b^2<c^2
8^2+14^2 ? 20^2
64+196 ? 400
260 < 400
The triangle is obtuse.
P = 2l + 2w
P = 2(x + 3) + 2(7)
P = 2(x) + 2(3) + 14
P = 2x + 6 + 14
P = 2x + 20
A = lw
A= 7(x + 3)
A = 7(x) + 7(3)
A = 7x + 21
