Answer:
A rectangle has a length 6m less than twice its width. when 5 m are added to the width, the resulting figure is a square with an area of 256m^2. find the distance of the original rectangle
width:: x
length:: 2x-6
-------
New width:: x+5
---
Equation:
(x+5)^2 =256 =16
16 is the original length
Answer:
B
Step-by-step explanation:
Answer: 46
Step-by-step explanation:
you just do 30 + 16
Answer:
x = 45°
Step-by-step explanation:
From the triangle given in the picture,
It's given that two sides of the triangle are equal so the triangle is an isosceles triangle.
By the property of isosceles triangle,
Opposite angles of the equal sides are equal in measure.
By triangle sum theorem,
x + x + 90° = 180°
2x + 90 = 180
2x = 180 - 90
x =
x = 45°
