Answer:

You got the first two correct, both negatives. But, number 15 is a positive.

Step-by-step explanation:

3)

ex.

\frac{ - 1}{ - 1}  =  + 1

\frac{ + 1}{ - 1}  =  - 1

In order to receive a positive at the end, the second step's (-1) needs to be placed with (+1).

\frac{ + 1}{ + 1}  =  + 1

Of course, the positive sign doesn't need to be put in front of the one, it is just used for visual purposes.

Westkost [7]

Answer:

x=95

Step-by-step explanation:

First, we can simplify the equation. 10c-760=190. We can +760 on both sides. 10c=950. We can do 950/10=95.

What is the value of x?
wolverine [178]

Since they are supplementary angles (180°)

45° + (2x-5)° = 180°

(2x-5)° = 180° - 45°

(2x-5)° = 135°

2x° = 135° - 5°

2x° = 130°

x° = 130/2°

x° = 65°

Plz hurry!!!! thank you!!!!
marin [14]

Answer:

∠A ≈ 19.47°

Step-by-step explanation:

As you know , the angle that tangent makes with the radius at the point of tangency is 90°.

∴∠OKA = 90°

As  AO = 15 and OK = 5 ,

sin(A) = \frac{OK}{AO}

sin(A) = \frac{5}{15}

sin(A) = \frac{1}{3}

∠A = sin^{-1} (\frac{1}{3} )

∠A ≈ 19.47°
