On his first try , a pole-vaulter cleared 3.7 meters. on his second try the pole-vaulter cleared 45 centimeters more than his first try. what height, in meters did the pole-vaulter clear on his second try show your work

a.3.25
b.3.745
c.4.15
d.8.2

Do 3.7 / 10, since metric units are 10 in comparison, and you get 37 decimeters , which in turn, you divide again by 10 to get centimeters, so 370 centimeters.
Then add 45 to that to get 415 centimeters. Then multiply that by 100 to get back to meters, so 4.15 meters

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
