Answer:

  • 30 cm²

Step-by-step explanation:

The shaded area is the difference of the total area and the white triangle.

The white triangle has base of 9 cm and height of 4 cm.

<u>Its area is:</u>

  • A = 1/2*9*4 = 18 cm²

<u>Area of rectangle:</u>

  • A = 12*4 = 48 cm²

<u>The shaded area:</u>

  • 48 - 18 = 30 cm²

In an equilateral triangle, the measure of each angle is 60 degrees. Then the value of x and y is 17/3 and 65.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In trianlge ΔMNP, PM = 3x - 4, MN = 14, ∠N = 5y - 5.

In an equilateral triangle, all the sides and all the angles are equal.

MN = NP = PM

∠M = ∠N = ∠P

Then we have

   PM = MN

3x - 4 = 14

      x = 17/3

We know in an equilateral triangle, the measure of each angle is 60 degrees. Then we have

    ∠N = 60

5y - 5 = 60

    5y = 65

      y = 13

Identify one similarity and one difference between the graph of y = 2x + 4 and the graph of y= -1/2x+4
Aleksandr-060686 [28]

Answer:

One difference would be the slope of the lines. One similarity would be where the lines cross the y-axis.

Step-by-step explanation:

This can be seen when we use the equation y=mx+b. m stands for the slope of the line and b stands for where the line is going to cross the y-axis.

I hope this helps.

The perimeter of an equilateral triangle is 48 centimeters, what’s the height to the nearest whole number?
Lerok [7]

Answer:

Height = 13.86 cm

Step-by-step explanation:

1. Find the length of each side

48/3 = 16

2. cut the triangle in half.

Base = 8 Hypotenuse = 16

3. use the formula A^2 + B^2 = C^2

(16^2 - 8^2)^(1/2) = 13.86 cm
