Answer:
Step-by-step explanation:
Since A = 50 degrees, c = 10 ,and since it is a right Triangle, then C = 90 degrees and so B = 180 - (90 +50)......... sum of angles of a triangle
B = 180 - 140
B = 40 degrees
Using sine rule : a/sin A = b / sin B = c / sin C
To calculate a, then we use a/ sin A = c / sin C , since we know c and C
i.e a/ sin 50 = 10 / sin 90
recall that sin 90 = 1
then we have a / sin 50 = 10 / 1
cross multiply
a = 10 x sin 50
a = 10 x 0.76604
a = 7.6604
We will calculate b following the same procedure
b/ sin B = c / sin C
b/ sin 40 = 10/ sin 90
b/ sin 40 = 10/ 1
b = 10 x sin 40
b = 10 x 0.64279
b = 6.4279
Therefore a ≈7.6604 , b ≈ 6.4279
Being simplified the answer is 30a^2b^3x^2.
Answer:
Yeah, D is the right anwser!
Step-by-step explanation:
I would be here for way to long to type up the explanation. And I don't have time to waste.
Hey!
Your answers are:
- 4 less than a number
- A number decreased by 4
Let k represent "a number". "k" is a variable, and variables are unknown.
-4 is subtracting 4. That means you're subtracting 4 from a number. -4 also means that the number is decreasing by 4. Therefore, those 2 are your answers.
<em>I hope this helps!</em>
Range= 4
Range is the highest number minus the lowest number, 10-6=4
