Step-by-step explanation:

6. angle 1 = angle 4 = 60deg (vertically opposite angles)

7. angle 3 = 180 - 40 - 60 = 80deg (angles on a straight line are supplementary)

8. angle 5 = angle 2 = 40deg (vertically opposite angles)

9. angle 6 = angle 3 = 80deg (vertically opposite angles)

10. angle 7 = angle 5 + angle 4 = 40 + 60 = 100deg (alternate angles, //lines)

11. angle 8 = 180 - 100 = 80deg (angles on a str line are supplementary)

12. angle 9 = 180 - 80 - 40 = 60deg (angles in a triangle)

13. angle 10 = 180 - 60 = 120deg (angles on a str line are supplementary)

14. angle 11 = angle 9 = 60deg (vertically opp angles)

15. angle 12 = angle 10 = 120deg (vertically opp angles)

How do you solve a distributive equation

nadya68 [22]

Let's say you are given the equation 4(x+5). What you must do is distribute the 4 to everything inside the parenthesis. What this means is that you multiply everything inside the parenthesis by the number outside the parenthesis (in this equation that would be 4). For example, the equation 4(x+5) would distribute as (4*x)+(4*5). This would then become 4x+20.

Two birds sit at the top of two different trees. The distance between the first bird and a birdwatcher on the ground is 32 feet.

mestny [16]

Answer:

x = 45.3°

Step-by-step explanation:

The distant between the first bird and the bird watcher is opposite to the reference angle, x° = 32 ft

The hypotenuse is the distance between the second bird and the bird watcher = 45 ft.

Therefore,

$sin(x) = \frac{opp}{hyp} = \frac{32}{45}$

$sin(x) = \frac{32}{45} = 0.7111$

$x = sin^{-1}(0.7111)$

$x = 45.3$

I’ll give 36 points to the person who answers this please

GREYUIT [131]

Hello!

These | | you are seeing means absolute value. Absolute value is the distance a number is from 0. For example, the absolute value of -3, or |-3|, would be 3 as -3 is 3 away from 0.

Therefore, we can look at these two operations. |-12|, and |8|

|-12| would equal 12, as -12 is 12 away from 0. |8| would equal 8, as 8 is 8 away from 0. 12 is greater than 8.

Therefore, your answer is the second choice, |-12|>|8|.

Hope this helps!
