Hi I need help please

Answer/Step-by-step explanation:

Recall: if two figures are similar, we know that the ratio of their areas = the square of the ratio of their corresponding sides

Apply this knowledge to solve the problems given.

✔️Problem 1 (4-sided polygon):

Let the missing area be x cm²

Therefore,

\frac{x}{9} = \frac{8^2}{4^2}

\frac{x}{9} = \frac{64}{16}

\frac{x}{9} = 4

Multiply both sides by 9

x = 9*4

x = 36 cm²

✔️Problem 2 (3-sided polygon):

Let the missing area be y cm²

Therefore,

\frac{y}{240} = \frac{8^2}{32^2}

\frac{y}{240} = \frac{64}{1,024}

\frac{y}{240} = \frac{1}{16}

Multiply both sides by 240

y = ¹/16 × 240

y = 15 cm²

✔️Problem 3 (5-sided polygon):

Let the missing area be z cm²

Therefore,

\frac{z}{40} = \frac{3^2}{2^2}

\frac{z}{40} = \frac{9}{4}

Multiply both sides by 40

z = \frac{9}{4} * 40

z = \frac{9}{1} * 10

z = 90 cm²

PLEASE HELP ANSWER ASAP

Answer:

x = 20

Step-by-step explanation:

Use Pythagorean Theorem to solve for x:

a^2 + b^2 = c^2

Plug in given values if a = 12, b = 16, and c = x (x is hypotenuse)

12^2 + 16^2 = x^2

(12*12) + (16*16) = x^2

144 + 256 = x^2

400 = x^2

Take square root of both sides to solve for x

sqrt(400) = sqrt(x^2)

20 = x or x = 20

Sonja's house is 4 blocks west and 1 block south of the center of town. Her school is 3 blocks east and 2 blocks north of the ce
lorasvet [3.4K]
The answer is √58 = 7.62

So, if you draw this down, you will see that the direct distance is hypotenuse c of a right triangle which sides are 3 blocks (1 south and 2 north) and 7 blocks (4 west and 3 east).
Use the Pythagorean theorem:
c² = a² + b²
a = 3
b = 7

c² = 3² + 7²
c² = 9 + 49
c² = 58
c = √58
c = 7.62
