Answer:
-14a
Explanation:
We are given 7(b - a) - 7(b + a).
We can distribute the 7’s to get:
7b - 7a - 7b - 7a
Combining like terms, we have:
-14a
Answer:
a
Step-by-step explanation:
Answer:
cos x
Step-by-step explanation:
sin x = (sin x) / (1) and cot x = (cos x) / (sin x)
Put those fractions next to each other and multiply them out (numerator times numerator, denominator times denominator).
Cancel out the (sin x) in the numerator and denominator
You should be left with just (cos x) / (1), whoch equals just (cos x).
Hope this helps!
Answer:
Simplifying
5x + 5x = 10x
Combine like terms: 5x + 5x = 10x
10x = 10x
Add '-10x' to each side of the equation.
10x + -10x = 10x + -10x
Combine like terms: 10x + -10x = 0
0 = 10x + -10x
Combine like terms: 10x + -10x = 0
0 = 0
Step-by-step explanation:
Answer:
U = 67.6 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos U = adj side / hypotenuse
cos U = sqrt(10)/ sqrt(69)
cos U = sqrt(10/69)
Taking the inverse cos of each side
cos ^-1( cos U) = cos ^-1(sqrt(10/69))
U = 67.62335
To the nearest tenth
U = 67.6 degrees
