Answer:

41° and 139°

45° and 145°

Step-by-step explanation:

Supplementary angles refers to two angles which measures up to 180°.

Therefore, it is safe to say that, angle in supplementary angles = 180°

23° and 147°

= 23° + 147°

= 170°

Not supplementary

41° and 139°

= 41° + 139°

= 180°

Supplementary angle

30° and 60°

= 30° + 60°

= 90°

Not supplementary angle

45° and 145°

= 45° + 145°

= 180°

Supplementary angle

Answer:

undefined

Step-by-step explanation:

f(x) = 2/ (-5x-10)

Let x = -2

f(-2) = 2/ (-5(-2)-10)

=2/(10-10)

What are the answers for question 1 and 2??

xeze [42]

Answer:

1) Answer: 3) $~~x = -3 \pm \sqrt{7}$

2) Answer: 3) 2 and -6

Step-by-step explanation:

$(x + 3)^2 = 7$

$x + 3 = \pm \sqrt{7}$

$x = -3 \pm \sqrt{7}$

Answer: $3)~~x = -3 \pm \sqrt{7}$

$2(x + 2)^2 - 4 = 28$

$2(x + 2)^2 = 32$

$(x + 2)^2 = 16$

$x + 2 = \pm \sqrt{16}$

$x + 2 = \pm 4$

$x + 2 = 4$ or $x + 2 = -4$

$x = 2$ or $x = -6$

Answer: x = 2 or x = -6

Find the area of the shaded region

AlexFokin [52]

Answer:

7 $\pi$ cm²

Step-by-step explanation:

First, find the area of the big circle with the formula A = $\pi$ r²

A = $\pi$ (3)²

A = 9 $\pi$

Now, we can find the areas of the smaller circles. Since they have the same radius, they are congruent (will have the same area)

A = $\pi$ r²

A = $\pi$ (1)²

A = $\pi$

Now, we will subtract the areas of the smaller circles from the area of the big circle to find the area of the shaded region:

9 $\pi$ - $\pi$ - $\pi$ = 7 $\pi$

So, the area of the shaded region is 7 $\pi$ cm²
