Answer:
3 - 3/5
Step-by-step explanation:
Cosine = adjacent/hypotenuse
So, in this case, cos=6/10=3/5
Youn could test all of the options by putting 8 and 3 in for a and b.
A. a - b = 5
8 - 3 = 5
5 = 5
B. a + b = 5
8 + 3 = 5
11 ≠ 5
C. a - b = 8
8 - 3 = 8
5 ≠ 8
D. a + b = 8
8 + 3 = 8
11 ≠ 8
As you can see, the only one that works is A. a - b = 5.
The answer to question 1 is here, I don't understand question 2 so I can't answer it.
Answer:
"Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.
Step-by-step explanation: Hope this helps
