Answer:

Step-by-step explanation:

Help you do what exactly?

Maybe prove that this is not really a valid triangle?

Easily done if we ASSUME that dimension 5 and 4 are valid, the third side of that triangle would be √(5² - 4²) = 3

Which means the other triangle would have legs of 9 and 12 - 3 = 9 making it an equilateral triangle not a right triangle.

If we assume sides 12 and height 4 are correct, then

A = ½(12)(4) = 24 units²

If we ASSUME that the outside legs are true, the the true height can be found using

√(5² - h²) + √(9² - h²) = 12

which resolves to about

h = 3.399

The area would be

A = ½(12)(3.399) = 20.394 units²

A VERRRY confusing question.

the difference between two numbers is 342. the bigger number is 4 times the smaller number. find the product of the two numbers.
SVETLANKA909090 [29]

Let the two numbers be x and y.

x = 4y

x - y = 342

3y = 342

y = 114

xy = 4y * y = 456 * 114 = 51984

find two consecutive odd integers that 7 times the smaller integer is 61 more than 2 times the larger integer.
Aleks04 [339]

Answer:

x = 13     smaller integer

x + 2 = 15  the other integer

Step-by-step explanation:

x = the smaller integer

x + 2 = the next integer          

7(x) = 61 + 2(x + 2)

7x = 61 + 2x +4

5x = 61 + 4

5x  = 65

x = 13     smaller integer

x + 2 = 15  the other integer

Find the measure of angel 3
Elena-2011 [213]

Answer:

100

Step-by-step explanation:

Remark

If two opposite arcs are given by being opposite vertically opposite angles, then the value of both the vertically opposite angles are equal to

Vertically opposite angle = 1/2 (arc1 + arc2)

Givens

Arc1 = 60

Arc2 = 100

Solution

The red dot angle = 1/2 (60 + 100)

The red dot angle = 1/2(160)

The red dot angle = 80

Because the red dot angle and <3 are on the same line with the same common point, they are supplementary.

<3 and red dot = 180

<3 + 80 = 180                          Subtract 80 from both sides

<3 = 180 - 80

<3 = 100
