Two surveyors are at the same altitude and are 10 miles apart on opposite sides of a mountain.
They each measure the angle relative to the ground
and the top of the mountain. Use the given diagram to
indirectly measure the height of the mountain.

1. whats 2/3 plus 1/9 2. 5/7 plus 1/2 3.7/15 plus 2/15

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
