The sum of interior angles in a triangle is 180°
42° + 67° + other angle = 180°
109° + other angle = 180°
other angle = 180° - 109°
other angle = 71°
The measure of the other angle is 71 degrees
Answer: 9 Presents
Explanation: 15/3 = 45/x.
Cross Multiply: 15x= (45)(3)
Simplify: x= 9
The answer is (20,0). We can determine the sum of two vector points by adding x1 to x2 and y1 to y2. This is like adding integers, the only difference is the answer is in vector form. In here, we have (x,y). x = 7+13 and y = 5+(-5). that is why we have the (20,0) as the answer.
