Answer:

12 square units

Step-by-step explanation:

We can break this shape into three parts, the left triangle, the middle square, and the right triangle. The left triangle has area of 2 square units, because 1/2(2x2) is 2. The middle square has 4 square units because 2x2 is 4. The right triangle has 6 square units because 1/2(6x2) is 6.

Adding the area of all the parts we get 12 square units.

Given that ABCD is a parallelogram, what must be proven to prove that the diagonals bisect each other?

Yuliya22 [10]

Answer:

We have to prove Δ ABO ≅ Δ CDO or, Δ DAO ≅ Δ BCO.

Step-by-step explanation:

Let us assume that ABCD is a parallelogram having diagonals AC and BD.

We have to prove that in a parallelogram the diagonals bisect each other.

Assume that the diagonals of ABCD i.e. AC and BD intersect at point O.

Therefore, to prove that the diagonals AC and BD bisect each other, we have to first prove that Δ ABO and Δ CDO are congruent or Δ DAO and Δ BCO are congruent.

In symbol, we have to prove Δ ABO ≅ Δ CDO or, Δ DAO ≅ Δ BCO. (Answer)

Given the following triangle find side AC. A. 11.89 B. 12.87 C. 13.98 D. 14.08

BigorU [14]

Answer:

The answer to your question is AC = 14

Step-by-step explanation:

To solve this problem, we must use trigonometric functions.

And we must look for a trigonometric function that relates the opposite side and the hypotenuse.

This trigonometric function is the sine

$sin\alpha = \frac{opposite side}{hypotenuse}$

solve for Opposite side = AC

AC = hypotenuse x sin α

- Substitution

AC = 25 x sin 34

- Simplification

AC = 25 x 0.56

- Result

AC = 14

Sidana [21]

Answer:

EF = 3.43

Step-by-step explanation:

Sin θ = opposite / hypotenuse

Sin 26 = EF / 4.5

0.762 × 4.5 = EF

EF = 3.43

Heather deposits $7000 into an account that pays simple interest at a rate of 2% per year. How much interest will she be paid in

german

Answer:

year after 3 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $7000.00.

r is the interest rate, 2% per year, or in decimal form, 2/100=0.02.

t is the time involved, 3....year(s) time periods.

So, t is 3....year time periods.

To find the simple interest, we multiply 7000 × 0.02 × 3 to get that:

The interest is: $420.00

Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),

or 7000.00 + 420.00 = 7420.00. For example:

If you borrowed the $7000.00, you would now owe $7420.00

If you loaned someone $7000.00, you would now be due $7420.00

If owned something, like a $7000.00 bond, it would be worth $7420.00 now.
