Answer:
x = 9
∠B = 7 x 9 - 1 = 62°
∠BCD = 120°
Step-by-step explanation:
exterior angle of a triangle is equal to the sum of two opposite interior angles
∠BCD = ∠CBA + ∠BAC
10x + 30 = (7x - 1) + (58)
10x + 30 = 7x + 57
3x = 27
x = 9
∠B = 7 x 9 - 1 = 62
∠BCD = 10 x 9 + 30 = 120
Answer:
its d, because there is no hypotenus in equiateral but there hypotenues in right triangle
Step-by-step explanation:
Hello!
hint: we can rewrite your function as below:
<span>3/<span>tan<span>(<span>4x−3π</span>) = </span></span></span>3(1+tan4xtan3π)/tan4x−tan3π =
=<span>3/<span>tan<span>(<span>4x</span>) = </span></span></span>3cot<span>(<span>4x</span><span>)
</span></span>now, since the period P of cotangent function is pi, then the period of cot(4x), which is the period of our original function, is such that:
<span>"4P=π"
Hope this Helps! Have A Wonderful Day! :)</span>
Answer: [C]: "<span>numbers which cannot be expressed as a ratio of integers."

There are a total of 10 marbles. Out of those 2 are yellow.
So, the probability of picking a yellow marble is 2/10, or 1/5 simplified.
As a percentage, this is 20%
Hope this helps :)
