I really need help with this, it's my last question. Please help!

Answer:
The measure of Angle M = 74.8°
Step-by-step explanation:
Cos(x) = [tex]\frac{adjacent}{hypotenuse}[/tex]
Cos(x) = [tex]\frac{26}{99}[/tex]
x = Cos⁻¹([tex]\frac{26}{99}[/tex])
x = 74.8°
So the measure of Angle M = 74.8°
Hope this helps!
Answer:
Trigonometry
since we have the adjacent and the hypotenuse we use CAH .We are looking for the angle we take the cos inverse
cos x = A
H
cos x = 26
99
x = cos -1 (26 ÷ 99)
x = 74.77404748
x= 74.8
