Answer:
Step-by-step explanation:
Distance between two points P(x1,y1) and Q(x2,y2) is given by: d(P, Q) = √ (x2 − x1)2 + (y2 − y1)2 {Distance formula} 2. Distance of a point P(x, y) from the origin is given by d(0,P) = √ x2 + y2.
The third angle would be 100 degrees
Explanation: 360-85-115-60= 100
Answer:
380
Step-by-step explanation:
.20x = 19 + .15x
.05x = 19
x = 380
The answer would be 480 and because you multiply 30 times 12 you will get 360 and then you add that to the money he already has which is 120 so the total amount is 480
