the sum of supplementary angles equals 180°

you can have an acute angle (less than 90°) + an obtuse angle (greater than 90°) equal to 180°

But you can also have a right angle (equal to 90°) + another right angle equal to 180°

Answer: (b) sometimes

Answer:

50m²

Explanation:

first, we have to find the length and width of the backyard. since 4cm represents 5m, we know that the real width of the backyard is 5m.

as for the length of the backyard, 8cm is double of 4cm so we can also double 5m to get 10m.

now, we can find the area by taking 5m × 10m = <u>50m²</u>.

i hope this helps! :D

Please help!<br> Hard math.

Reil [10]

Answer:

the value of digit 3 in 156.32 =

3 x 0.1 = 0.3

The value of digit 3 in 13 =

3 x 1 = 3

3/0.3=10 times

The value of digit 3 in 13 is 10 ten times the value of digit 3 in 156.32

As long as the (digit in ones/single digit) of a number is equal to 3

The value of digit 3 of it is always 10 ten times the value of digit 3 in 156.32

Given a point A(-3,-1), it is dilated by some scale

Sidana [21]

Answer:

$B' = (-3, -15)$

Step-by-step explanation:

Given

$A = (-3,-1)$

$A' = (-9,-3)$

$B = (-1,-5)$

Required

Determine the coordinates of B'

Since A' is the image of A; we need to first calculate the scale factor using

$A' = A * Scale\ factor$

Make Scale Factor the subject

$Scale\ Factor = \frac{A'}{A}$

Substitute values for A' and A

$Scale\ Factor = \frac{(-9,-3)}{(-3, -1)}$

Factorize the numerator

$Scale\ Factor = \frac{3 * (-3,-1)}{(-3, -1)}$

$Scale\ Factor = \frac{3 * 1}{1}$

$Scale\ Factor = 3$

The coordinates of B' is then calculated as follows:

$B' = B * Scale\ Factor$

Substitute values for B and Scale Factor

$B' = (-1,-5) * 3$

$B' = (-3, -15)$
