Answer:
The inequalities all need to be of the form a < x ≤ b. i think that is it
B. The measure of angle w is the same as the measure of angel z
A) 51, assuming this is a *right* triangle:
38^2+34^2 = 50.99^2, rounding 51!!
3^(4x) = 3^(5 - x)
4x = 5 - x
4x + x = 5
5x = 5
x = 5/5 = 1
x = 1
Answer:
sin 2x + cos x = 2 sin x cos x + cos x = (2 sin x + 1)cos x
Step-by-step explanation:
Given the expression: sin 2x + cos x,
then we can use the formula: sin 2x = 2 sin x cos x, which gives:
sin 2x + cos x = 2 sin x cos x + cos x = (2 sin x + 1)cos x
So there you have two expressions in terms of sin x and cos x, as requested. :D
