Am I finding the area of this wierd shape correctly if not what am I doing wrong?

Mathematics
1 answer:
saw5 [17]3 years ago
3 0

Answer:

8 ft^2

Step-by-step explanation:

Sadly, you are doing this incorrectly.

The easiest way to find the area of this shape is to separate it into a square and a triangle.

This will leave you with a square with the dimentions 2x2 a triangle with a base of 4 and a height of 2.

The area of the square is 4 ft^2

Using the equation for the area of a triangle

A=\frac{1}{2} bh

We can plug in our 2 know values to get

A=\frac{1}{2} (4)(2)\\A=4

Now we can take the sum of the areas of these two shapes to get a total area of 8 ft^2

Seth is using the figure shown below to prove Pythagorean Theorem using triangle similarity. In the given triangle ABC, angle A
lana66690 [7]

The relationship between the lengths of the sides of a right triangle are

given by Pythagoras theorem.

  • Part A: <u>ΔABC is similar to ΔADC</u>
  • Part B: ΔABC and ΔADC are similar according <u>AA similarity postulate</u>
  • Part C: <u>DA = 6</u>

Reasons:

Part A:

∠A = 90°

Segment AD ⊥ Segment BC

Location of point D = Side BC

Part A: In triangle ΔABC, we have;

∠A = 90°, ∠B = 90° - ∠C

In triangle ΔADC, we have;

∠ADC = 90°, ∠DAC = 90° - ∠C

∴ <u>ΔABC is similar to ΔADC</u> by Angle-Angle, AA, Similarity Postulate

Part B: The triangles are similar according to <u>AA similarity postulate</u>,

because two angles in one triangle are equal to two angles in the other

triangle and therefore, by subtraction property of equality, the third angle

in both triangles are also equal.

Part C: The length of DB = 9

The length of DC = 4

Required: Length of segment DA

In triangle ΔABD, we have;

∠BDA = 90°= ∠ADC

∠DAC ≅ ∠B by Congruent Parts of Congruent Triangles are Congruent

Therefore;

ΔABD ~ ΔADC by AA similarity, which gives;

\displaystyle \frac{\overline{DA}}{\overline{DC}}  = \frac{\overline{BD}}{\overline{DA}}

\overline{DA}^2 = \overline{DC} \times \overline{BD}

Which gives;

\overline{DA}^2 = 4 × 9 = 36

\overline{DA} = √(36) = 6

\overline{DA}<u> = 6</u>

What is the decimal equivalent of 6/13 ? Round to tenths place. If answer doesn't
Arte-miy333 [17]

Answer:

0.5

Step-by-step explanation:

6/13 is the same as saying 6 ÷ 13

6 ÷ 13 = 0.4615384615

The first position after the decimal is the tenths column. Round up, because 6>5.

Factorise the following​
Irina18 [472]

Answer:

see explanation

Step-by-step explanation:

(a)

2x + 10 ← factor out 2 from each term

= 2(x + 5)

(b)

5x - 15 ← factor out 5 from each term

= 5(x - 3)

(c)

8x + 6 ← factor out 2 from each term

= 2(4x + 3)

(d)

12x - 8 ← factor out 4 from each term

= 4(3x - 2)
