Consider the given triangle. If a = 83 and b = 70, then the measure of ZB =​

If ZB is the 3rd angle, since a triangle has 180 degrees total just do 83+70+x=180 s x=27

Step-by-step explanation:

Step-by-step explanation:

The tower represents the short side of a 30°-60°-90° right triangle. The distance from the tower represents the long leg, not the hypotenuse, of that triangle. It is √3 times the short side. In this geometry, man B is 100√3 = 173.2 meters from the tower.

The tower represents one of two congruent sides of a 45°-45°-90° right triangle. Man A will be standing 100 meters from the tower.

The distance between A and B is 100 +173.2 = 273.2 meters. The men are about 273 meters apart.
