it cannot be solved because 7 < 15 as we know hypotenuse > base

Answer:
cos theta=15/7
cos theta = Adjacent/Hypotenuse
Adjacent = 15
Hypotenuse = 7
By pythagorus theorem
H^2=O^2 + A^2
O^2 = H^2 - A^2
O^2 = 15^2 - 7^2
O^2 = 225 - 49
O^2 = 176
O=√176
O=4√11
sin theta = 4√11/7
tan theta = 4√11/15
Hope u got ur answer
