Answer:
AB ≈ 35.93
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos3.5° = 
= 
= 
Multiply both sides by 36
36 × cos3.5° = AB, thus
AB ≈ 35.93 ( to 2 dec. places)
Answer:
12= ax - x + b
Step-by-step explanation:
5x -4(x - 3) - 8 = ax + b
5x -4x + 12 - 8 = ax + b
x + 12 = ax + b
12= ax - x + b

Step-by-step explanation:
Answer:
40 cm by 44 cm
Step-by-step explanation:
A square sheet of paper has area 1600 cm^2.
area = s^2
1600 cm^2 = s^2
s = sqrt(1600 cm^2)
s = 40 cm
The side of the square was 40 cm, so the square measured 40 cm by 40 cm.
One side of 4 cm short, so the paper should have been 40 cm by 44 cm.
