Given age, one can not determine the height. In another words, students with same age may have different height
Answer:
54 degrees
Step-by-step explanation:
I know this because complementary means both angles equal 90 degrees so we know the angle A is 36 degrees so you subtract 36 from 90 and get 54, so angle B is 54 (i know this is right because i got a 100)
Answer:
A = (x^2 - 2x - 8) m^2
Second option
Step-by-step explanation:
Area of rhombus = 1/2 d1 * d2
= 1/2(2x+4)(x-4)
= 1/2 (2x^2 -8x + 4x - 16)
= 1/2 (2x^2 - 4x - 16)
= x^2 - 2x - 8
