The formula for the area of a triangle of base b and altitude h is A = (1/2)(b)(h).
Here, b = 18 cm and h = 9 cm. Thus, the desired area is:
(18 cm)(9 cm)
A = ----------------------- = 81 cm^2
2
This problem gives you more info than is needed to solve it. The area of the given triangle is 81 cm^2.
Some key definitions:
<u>Reflexive property:</u> angles, line segments, shapes are congruent to themselves. Its easier to think of a shape: if you have a circle, then this circle is equal to itself.
<u>Symmetric property:</u> you can interchange the equal signs of an equation. So think of a=b is the same as b=a, its just the same thing written in a different order.
<u>Transitive property:</u> If a=b, and b=c, then a=c. Basically think of it as a=b=c, all of these variables are the same as each other.
So for the first clue, you have the reflexive property.
The second clue is the symmetric property.
The third clue is the transitive property.
Hey there!
Here's your answer: m<2=114.52 degrees
Here's how I got it: we know that a linear pair of angles is supplementary, aka the sum of the angles is 180 degrees.
you would add 18x-1 and 23x+7 together to equal 180 and solve for x.
then, you would substitute x for 4.24 (rounded) into 23x+17
23(4.24)+17=114.52

Assuming she did a checkered pattern if she got 10 red tiles she would need 20 tiles total if the kitchen was a square.
There seems to be some sort of missing information here or maybe a missing picture. Either way, I hope this helps.
Opposite the 60: 9 square roots of 3 and the hypotenuse is 18
