Answer:
12/5
Step-by-step explanation:
tan A = opp/adj
For angle theta, 12 is the opposite leg.
13 is the hypotenuse.
We were not given the length of the adjacent leg, but we can use the Pythagorean theorem to find it.
a^2 + b^2 = c^2
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 25
The adjacent leg has a length of 5.
tan theta = opp/adj
tan theta = 12/5

What exactly is your question?
Answer:
-5
Step-by-step explanation:
Following the order of PEMDAS, you will multiply what is in the parentheses, then subtract what is in the parentheses, then finally subtract the whole thing.
(6×3 - 7×2) - (-7×4 + 7×3 + 8×2)
(18 - 14) - (-28 + 21 + 16)
(4) - (9)
-5
Step-by-step explanation:
Remember the Difference of Squares:
a² - b² = (a + b)(a - b)
Therefore (√20 - √3)(√20 + √3)
= (√20)² - (√3)² = 20 - 3 = 17. (C)
