What is the length of the hypotenuse of the triangle below

sdas [7]

Answer:

Step-by-step explanation:

Pythagorean Theorem

a^2 + b^2 = c^2

8^2 + 15^2 = c^2

64 + 225 = c^2

c^2 = 289, c = 17

8, 15, 17 is also a common Pythagorean triple.

Please answer all 3 questions

blsea [12.9K]

Answer:

x = 30°
DB = 26
AD = BC = AB = DC = 7

Step-by-step explanation:

<em>Diagonals of a square are congruent and perpendicular and bisect each other</em>

m∠AEB = 3x

m∠AEB = 90°

3x = 90° ⇒ x = 30°

AE = 3x - 2

EC = 2x + 3

AE = EC
3x - 2 = 2x + 3
3x - 2x = 3 + 2
x = 5

DB = EC = 2(AE) = 2(3*5 - 2) = 2(13) = 26

<u>AD and BC are the sides, which are equal</u>

2x - 1 = 5x - 13
5x - 2x = 13 - 1
3x = 12
x = 4

AD = BC = AB = DC = 2*4 - 1 = 7

Can someone help! I know the answer I just need step by step!

baherus [9]

Answer:

$4 \sqrt{2}$

Step-by-step explanation:

Rewrite 32 as the product of 16 and 2:

$\implies \sqrt{32}=\sqrt{16 \cdot 2$

Apply exponent rule $\sqrt{a \cdot b}=\sqrt{a}\sqrt{b}$

$\implies \sqrt{16 \cdot 2}=\sqrt{16}\sqrt{2}$

Rewrite 16 as 4²:

$\implies \sqrt{16}\sqrt{2}=\sqrt{4^2}\sqrt{2}$

Apply exponent rule $\sqrt{a^2}=a$

$\implies \sqrt{4^2}\sqrt{2}=4 \sqrt{2}$

The area of two similar octagons are 4 m2 and 25 m2. What is the scale factor of their side lengths

mylen [45]

Answer:

The scale factor of the sides of the Octagon is 2:5

Step-by-step explanation:

Both these octagons can be considered as the combination of 8 similar triangles joined edge to edge.

We know this property of similar triangles, that the ratio of area of similar triangles is proportion to the square of the ratio of sides of the similar triangle.

$Side_{1} ^{2} : Side_{2} ^{2} =Area_{1} : Area _{2}$

From the above property, we plug in the values

$Side_{1} ^{2} : Side_{2} ^{2} =4: 25$

$Side_{1} : Side_{2} =2: 5$

Therefore, the ratio of the sides of the Octagon are 2:5.
