If you look closely, you can see that both angles b and the 43 degree angle together make a right angle. (You can tell this by the red line.) A right angle is 90 degrees. To solve this, all you would have to do is take the 90 (both angles combined) and subtract it by the number you already have (43).
Angle b = 47 degrees.

Answer:1.28
Step-by-step explanation:
Answer:
1. D- All of the above
2. B- The material the acid is poured on
3. C- Mass of the ball
4. A- Temperature
Step-by-step explanation:
2. The control variable is what stays the same so the material the acid is poured on must be the same as different materials have different reactions to acids.
3. The independent variable is what's being changed and in this experiment the mass of the ball is changed each time
4. The independent variable is what's being changed and in this experiment the temperature is different in each cup.
Hope this helped! :)
Negative numbers can't have real number square roots, but negative numbers can have real number cube roots! What is the cube root of −8? because . Remember, when you are multiplying an odd number of negative numbers, the result is negative! In the example below, notice how is used to simplify the radical.
