Answer:
None
Step-by-step explanation:
We are given a triangle ABC with ∠A = 30°, sides a = 4 and b = 10.
According to the 'Law of Sines- Ambiguous Case', we have,
If a < b×sinA, then no triangle is possible.
If a = b×sinA, only one triangle is possible
If a > b×sinA, two triangles are possible.
So, we have,
b×sinA = 10 × sin30 = 10 × 0.5 = 5.
Now, as
4 = a < bsinA = 5.
We get, according to the rule, no triangle is possible.
Answer:
The sequence is arithmetic with a common difference of -10
Step-by-step explanation:
From the question, we want to determine if the sequence is arithmetic or geometric
From the question
f(1) = 5
f(2) = -5
f(3) = -15
Mathematically for the common difference;
f(3) - f(2) = f(2) - f(1)
Since;
-15-(-5) = -5-5
-10 = -10
Since the common difference here is same , then the sequence is arithmetic with a common difference of -10
Act like the two triangles are one and to find z and find the others find z first comment if you didn’t understand and I will go into it with more detail
√3(√6)
= √3(6)
=√3(3·2)
=3√2
B. No the product will not be rational as 3√2 cannot be expressed as a simple fraction
Answer:
Step-by-step explanation:
sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x
= 1
