Answer:

21.9

Step-by-step explanation:

The altitude of an isosceles triangle bisects the base. So, x represents the hypotenuse of a right triangle with legs of 9 and 20. It can be found using the Pythagorean theorem:

x^2 = 9^2 +20^2 = 81 +400

x = √481 ≈ 21.932

The length x is about 21.9 units.

Answer:

$3x=78+(x-2)$

Step-by-step explanation:

The complete question in the attached figure

we know that

The Triangle Exterior Angle Theorem states that: An exterior angle of a triangle is equal to the sum of the opposite interior angles.

In this problem

$3x=78+(x-2)$

solve for x

$3x=76+x\\3x-x=76\\2x=76\\x=38^o$

How do you determine where to place the decimal point in the product?

frez [133]

Let's look at an example:

2.24 x 21.6

$2.24\\ 21.6\\ ______$

Do normal multiplication and get

48384 This is not correct, until we put the decimals in. To know how to do this, count the number of decimal spaces from the factors. In 2.24, there are 2, because .24. In 21.6 there are 1 because of .6. This mean three places, so 48384 becomes

48.384
