Answer:
z^3 • z^3 ? or z^3^2 ?
Step-by-step explanation:
let the short side = x
Long side = 3x
Middle side = 3x -3
x + 3x + 3x -3 = 32
Simplify:
7x -3 = 32
Add 3 to both sides:
7x = 25
Divide both sides by 7:
X = 5
answer: shortest side = 5cm
first step to remove brackets
here write them in serial order,
=5x²+3x+4+5x²+5x-1
=5x²+5x²+3x+5x+4-1
=10x²+8x-3
The measure of the angle ∠ABC is 110° and the measure of the reflex angle ∠CBD is 70°.
<h3>What is an angle?</h3>
Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
The measure of the angle ABC will be
∠ABC = 110°
The angle ∠ABC and ∠CBD are the linear angles. Then we have
∠ABC + ∠CBD = 180°
110° + ∠CBD = 180°
∠CBD = 70°
