what is the value of cosΦ?
Explain your answer. ​

Answer 1

37°

in a right angle triangle;

37 and 53 are complementary angles and we know that 3 4 5 are Pythagorean triads and if the opposite side to theta is greater (4) theta becomes 53° and if opposite side to theta is smaller (3) it becomes 37°.

now above opposite side is 4 so its 53°

then straight line is 180 ° so

90° + 53° + x = 180°

this gives x = 37°

hence solved
