Hello everyone,

My name is Alex! I am taking the class algebra 2/ trigonometry honors! I have just finished the algebra 2 section of the class and am moving onto the trigonometry section of the class! Will any of you fine gentlemen be so kind as to help a child like myself with a few simple math problems I cannot understand? Thank you in advance!

12. A force of 176 lbs. Makes an angle of 78°50’ with a second force. The resultant of the two forces makes an angle of 41°10’ with the first force. Find the magnitude of the second force and the resultant.

14. A crate is supported by two ropes. One rope makes an angle of 46°20’with horizontal and has a tension of

89.6 lbs. on it. The other rope is horizontal. Find the weight of the crate and the tension in the horizontal

rope.

15. Two people are carrying a box, one on each side of the box. One person exerts a force of 150 lbs. at an

angle of 62.4° with horizontal. The other person exerts a force 114 lbs. at an angle of 54.9°with horizontal.

Find the weight of the box.

I have the answers to the questions above but I do not understand how to get them! Please show work if you can! Thanks again!
