P=2L+2W
80=2*26+2W
so then you could find the missing number of W which is
W=14
The measurement of AB is 16.23.
Solution:
Given ACB is a right angled triangle.
AC = 10, ∠C = 90° and ∠A = 52°.
cos θ ≈ 0.616
Here AC is the base and AB is Hypotenuse.
To find the length of AB:
![$\cos\theta=\frac{\text{Base}}{\text{Hypotenuse}}](https://tex.z-dn.net/?f=%24%5Ccos%5Ctheta%3D%5Cfrac%7B%5Ctext%7BBase%7D%7D%7B%5Ctext%7BHypotenuse%7D%7D)
![$\cos 52^\circ=\frac{10}{AB}](https://tex.z-dn.net/?f=%24%5Ccos%2052%5E%5Ccirc%3D%5Cfrac%7B10%7D%7BAB%7D)
![$0.616=\frac{10}{AB}](https://tex.z-dn.net/?f=%240.616%3D%5Cfrac%7B10%7D%7BAB%7D)
Do cross multiplication, we get
![$AB=\frac{10}{0.616}](https://tex.z-dn.net/?f=%24AB%3D%5Cfrac%7B10%7D%7B0.616%7D)
AB = 16.23
Hence the measurement of AB is 16.23.
