Answer:
B. 24 :)
Step-by-step explanation:
I hope this helps!
M<J = m<N ( alternate angles)
m<K = m<M ( alternate angles)
so the third angles must also be equal ( total 180 degrees in each triangle)
Therefor the triangles are similar
Answer:
Triangle = 180 Degrees, so 77.
Step-by-step explanation:
42+35+x=180
x = 77
Step-by-step explanation:
sec x − cos x
Secant is the inverse of cosine:
(1 / cos x) − cos x
Find the common denominator:
(1 / cos x) − (cos² x / cos x)
Subtract:
(1 − cos² x) / cos x
