7-18= a negative number. We know that it'll equal a negative number because the minued(7) is less than the subtrahend(18), which results in a negative number (if both are positive).
We can make an addition problem from this. We can have 18 turn negative and 7 stay positive, and we'll get the same answer.
7+-18=7-18
7-18=7+-18=11
First think out the equation, once you've done that multiply 3 by 25 to get 75
<span>m?ABC = 60°
Looking at the diagram, you have triangle ABC. For m?BAC you are given a value of 75°, m?ACB is a supplementary angle to 135° which means it has a value of 180° - 135° = 45°.
Finally, ?ABC is the 3rd angle of triangle ABC. Since all the angles in a triangle add up to 180°, you simply need to do the subtraction.
180° - 75° - 45° = 60°
Therefore m?ABC = 60°</span>
