Answer:
Step-by-step explanation:
A right triangle with one acute angle measuring 30° is the 30°-60°-90° "special" triangle. The ratios of its side lengths are well known to be ...
1 : √3 : 2
<h3>Side lengths</h3>
In the given triangle, the longest side is labeled 10, so is 5 times the measure of the longest side in the ratios given above. Multiplying those ratio values by 5, we have side lengths ...
a : b : c = 5 : 5√3 : 10
That is ...
a = 5
b = 5√3
__
<em>Additional comment</em>
If you want to figure the side lengths using trigonometry, you have ...
a = c·sin(30°) = 10·(1/2) = 5
b = c·cos(30°) = 10·(√3/2) = 5√3
Answer:
10
Step-by-step explanation:
A coefficient is a multiplicative factor. Whatever is in front of the variable is a coefficient
Answer:
a^2 + 9a + 20
Step-by-step explanation:
The answer is D. because they are both the same ratio by squared-
6 squared is 36 and 11 squared is 121
So it's 6:11::36:121
