Step-by-step explanation:
80 I’m sorry if it’s wrong but I’m pretty sure I’m right
Given:
In triangle MNO, angle ONM is a right angle. Angle NOM is 40 degrees and angle LMN is 50 degrees.
To find:
The value of cos(M).
Solution:
In a right angle triangle,

Draw a diagram using the given information.
In triangle MNO, angle ONM is a right angle so its opposite side MO is the hypotenuse. For vertex M, MN is the base of the triangle. So,

Therefore, the correct option is B.
A pentagon, 5 sides, all internal angles add up to 720°, so wen u do the maths, X=5
