The area of a rectangle in 24 square units. A diagonal drawn from one corner to another divides the rectangle into two right tri
Natasha2012 [34]

Hello from MrBillDoesMath!

Answer:

12


Discussion:

The two triangles shown are congruent by the SAS postulate so the area of a single triangle is one-half that of the rectangle.  That is,

Area = (1/2) * 24 = 12


Thank you,

2. The variable expressions represent the angle measures of a triangle. Find the measure of each angle. Then classify the triang
Umnica [9.8K]

Answer:

Step-by-step explanation:

The triangle KLM is shown in the attached photo. The sum of the angles in a triangle is 180 degrees. It means that

angle K + angle L + angle M = 180 degrees. Since

m angle K=(10x+10). m angle L=(9x-3). m angle M=(7x-9), then

10x + 10 + 9x - 3 + 7x - 9 = 180

10x + 9x + 7x = 180 + 9 + 3 - 10

26x = 182

x = 182/26

x = 7

m angle K=(10x+10) = 10×7 + 10 = 80 degrees

m angle L=(9x-3) = 9×7 - 3 = 60 degrees

m angle M=(7x-9) = 7×7 - 9 = 40 degrees.

The triangle is an acute triangle because each angle is lesser than 90 degrees

The triangle is scalene triangle because non of the sides are equal.

If the height of the cylinder is halved and the diameter is double, by what factor will the volume of the cylinder change
uysha [10]
Let the radius be: r and height  be h 
volume =  πr²
if the radius is halved then radius = r/2
and height is doubled, so height= 2h
volume = πr*r/4*2h             = π*r²*h/2
Thus the volume will be halved.
