42-9=33 so 43-?=33
43-33=10 so 43-10=33
Answer:
Step-by-step explanation:
I will ASSUME that the units on 53 is angular degrees (53°) and that the internal angle below x is 90°
The drawing is certainly not to scale
sin53 = x / 49
x = 49sin53
x = 39.1331399...
x = 39 units (same units as 49)
Answer:
Perimeter=![22x+2y](https://tex.z-dn.net/?f=22x%2B2y)
Step-by-step explanation:
Given:
length of the rectangle= ![4x + 3y](https://tex.z-dn.net/?f=4x%20%2B%203y)
Width of the rectangle= ![7x - 2y](https://tex.z-dn.net/?f=7x%20-%202y)
Perimeter of a rectangle= 2(length+width)
Perimeter ![=2(4x+3y+7x-2y)\\\\=2(11x+y)\\\\=22x+2y](https://tex.z-dn.net/?f=%3D2%284x%2B3y%2B7x-2y%29%5C%5C%5C%5C%3D2%2811x%2By%29%5C%5C%5C%5C%3D22x%2B2y)
So, the expression of the perimeter of given rectangle is:
![22x+2y](https://tex.z-dn.net/?f=22x%2B2y)
