Answer:
B) 39/89
Step-by-step explanation:
The question above is on trigonometry.
Cosine of an angle is obtained using the CAH of SOHCAHTOA formula of trigonometry. It is obtained from the ratio of adjacent and hypotenuse of the triangle. Thus, CAH is a denotation of cosine formula; as stated below.
Therefore from the given shape,
Thus, the cosine of angle E = 39/89 (B)
Answer:
Choice C is correct
Step-by-step explanation:
We use the law of exponents in this problem;
Therefore,
Since the base is the same, that is 9, we simply add the exponents 1/2;
one-half plus one-half is equal to unity and any number raised to one is simply equal to the given number;
Answer:
(-1, 5)
Step-by-step explanation:
What you do is you start at the point (-4, 8). You then have to go 3 units right which will be -1. Then you will go 3 units down which is 5.
Your answer is (-1, 5).
Answer:
area of the triangle= 1/2 × base × height
24 = 1/2 × 4 × height
height. = 24/2
= 12 inches
answer is third option
