Answers: For the yellow one it’s 14
For the red one it’s 15

Long answer: so the way to do this is to find the ratio. So you look at the filled shape for the yellow ones case it’s the smaller one and the sides have a ratio of 9:6 or 3:2, now since on the other similar shape the 9 lines up with 21 we can divide that by 3 getting us 7 and multiply that by 2 and get 14.

For the red one it’s the same process, 8:6=4:3 so we and we divide 20 by 4 and get 5, then multiply that be 3 and get 15.

Please mark brainliest if this helps.

Which is a point on the circle whose center is (0, 0) and whose radius is 5?
AleksAgata [21]
Circle equation is given in the form of (x-a)²+(y-b)² = r²

Where (a, b) is the centre and 'r' is the radius

We have a circle with centre (0, 0) and radius of 5.

Substituting these value into the equation form, we have

(x-0)²+(y-0)² = 5²
x² + y² = 25

Hence, the equation of the circle is x² + y² = 25

How to solve this question ​
yarga [219]

Answer:

BC = 3.6

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{BC}{DE} = \frac{AC}{AE} , substitute values

\frac{BC}{1.2} = \frac{4.5}{1.5} ( cross- multiply )

1.5 BC = 5.4 ( divide both sides by 1.5 )

BC = 3.6
