Let's create this right triangle.  We will call it triangle ABC with angle B as the right angle, angle A being the larger of the angles A and C.  If the ratio is 5:4, then it is A:C.  5+4 = 9.  The measure of the right angle, angle ABC = 90, and 90 divided by 9 is 10.  So angle A is 5 * 10 which is 50 degrees, and angle C is 4 * 10 which is 40 degrees.  The smallest angle, angle C, is 40 degrees.

Answer:

Length = 12 inches, height = 3 inches

Step-by-step explanation:

First, you have to set up a proportion. 2/7, x/42.

Then, you cross multiply and get the setup of 84=7x

Finally, you divide 84 by 7 and get 12.

12 is the length, and there is no other answer that has 12 in the height. You could just do the same proportion to get 3, though.

What is the area of this figure?
matrenka [14]
There is 2 figure here, a triangle and a parallelogram.
Area of parallelogram=base * height
                                   A=9 * 5
                                   A=45m²
Area of triangle= \frac{1}{2} (base * height)
                        A=\frac{1}{2} (9*8)
                        A=\frac{1}{2}72
                        A=36m²
36+45=81m²
The area of this figure is 81m²

What is a short method to show the compound inequality x < 2 AND x > 7
jeyben [28]

These inequalities are not compatible: you are looking for a number that is less than 2, but more than 7. This is impossible, because if a number is less than 2, it can't be more than 7.

Conversely, if a number is more than 7, it can't be less than 2.
