Drop a perpendicular from an obtuse vertex.

That makes a 30 - 60º right triangle, with hypotenuse 6 and short leg 3. So the long leg, which is the height of the rhombus, is 3√3 .

Since a rhombus is a parallelogram, its area is base x height = 6 x 3√3 = 18√3

Select the property of equality used to arrive at the conclusion <br> if x-3=7 , then x=10
Fantom [35]

Answer:

The addition property of equality  

Step-by-step explanation:

According to the addition property of equality, if we add the same number to each side of an equation, the equality is still true.

We are given the equation

x – 3 = 7, and we must solve for x.

We want to get x by itself, so we <em>add 3 to each side</em>.

x – 3 + 3 = 7 + 3

             x = 10

We have just used the addition property of equality.

Aloiza [94]

Answer:

The answer is "\bold{\frac{22}{171}}"

Step-by-step explanation:

There are 22 million males that have completed four years of undergraduate, according to the data below: (or more). This is predicated on a population of 171 million.

The chances we're searching about \frac{(22\ million)}{(171\ million)} = \frac{22}{171}

however

This proportion could be further reduced because 22 and 171 have no common features (other than 1).
