It’s negativeeeeeeeeeeeeeeee
The mass of the apple juice needed to increase the initial concentration to 25% is 45 kg
The given parameters;
- <em>Mass of the apple juice, m = 30 kg</em>
- <em>current percentage, = 10%</em>
- <em>final percent after increment = 25%</em>
Let the mass added to increase the percentage to 30% = x
10% ----------------- 30 kg
25% ------------------ ?

The additional mass is calculated as;

Thus, the mass of the apple juice needed to increase the initial concentration to 25% is 45 kg.

Answer:
75 degrees
Step-by-step explanation:
I know the measure of the triangle's third angle is 75 degrees because all the angles of a triangle add up to 180 degrees. So, I did 180-62-43 and got 75. So, in order for this triangle to be true, the third triangle would have to be 75 degrees.
To check: 43 degrees+ 62 degrees+ 75 degrees = 180 degrees.
