We have to contruct two angle bisectors of the triangle.

various steps to inscribe the circle in a triangle are

  1. First draw a triangle
  2. Draw angle bisector of one angle
  3. Draw angle bisector of another angle
  4. Extent these angle bisectors, where they meet that point will be called the incenter
  5. From incenter draw prependicular to any side of the triangle
  6. The length from the point where the prependicular touches the side of triangle to the point of incenter will be radius.
  7. Use this radius and draw the incircle.

Deanna has $150.00 in her account.At the end of each week, she plans to take $15.00 out of her account for her spending money. W
AlexFokin [52]

Let the balance = Y and the number of weeks = x

She takes out 15 per week, so multiply 15 by x ( the number of weeks) to get 15x.

You would then want to subtract that from the amount she started with in her account.

The equation becomes: Y = 150 - 15x

Write the algebraic expression that matches each graph.
goldfiish [28.3K]

Answer:

f(x) = |x - 2| - 2

Step-by-step explanation:

Based on the shape of the graph, it's an absolute value function.

so the template for it is f(x) = |x|

From there, you can make some additions to show how much the graph has shifted from the template equation

since the graph went over to the left by 2 units and down by 2 units, this is added into the equation as follows:

f(x) = |x - 2| - 2

Find the area of the figure.<br><br> answer choices:<br> 31 ft², 80 ft², 40 ft², 60 ft²
IrinaVladis [17]

Answer:

60 ft²

Step-by-step explanation:

You can divide the figure into 2 parts.

First, solve for the rectangle: Area of a rectangle = b*h = 4ft x 10ft = 40ft²

Then, solve for the triangle:

Height = 10ft - 5ft = 5ft

Base = 12ft - 4ft = 8ft

Area of a triangle = (b*h)/2 = (5ft x 8ft)/2 = 20ft²

Just add them together: 20ft² + 40ft² = 60ft²

:)
