Answer:
I think it's 4/10 which is 0.4
Step-by-step explanation:
The following correct answer is c.
This I because when you translate using this, you first start with the point (0,0), translate that point down 3 (-3 means down three when outside parenthesis) and translate it to the right 4 units (this shown in a paraptosis, and when you move to the right you say -4, but if you move to the left you say +4)

Answer:
30°
Step-by-step explanation:
The relationship between triangle sides and angles can be remembered using the mnemonic SOH CAH TOA. Here, we're interested in the relationship involving the hypotenuse and the side opposite the angle:
Sin = Opposite/Hypotenuse
For a ramp 1 m high and 2 m long, we have ...
sin(x) = (1 m)/(2 m) = 1/2
x = arcsin(1/2) = 30°
The elevation angle of the ramp needs to be 30°.
Answer:
1) y° = 58°, x° = 85°
2) y° = 42°, x = 15°
Step-by-step explanation:
1) To find y° look at the right triangle with the other angle at 32°
32° + 90° + y° = 180°
y° = 180° - 122° = 58°
Now the other triangle contains
27° + y° + (180 - x°) = 180, plug for y°
27 + 58 + 180 - x = 180
x° = 85°
2) To find y°, add angles
65 + 31 + 2y = 180
96 + 2y = 180
2y = 84
y° = 42°
To solve for x°, add inside angles to 180
4x - 1 + 90 + 31 = 180
4x = 60
x = 15°
