Answer:
![a = 5](https://tex.z-dn.net/?f=a%20%3D%205)
Step-by-step explanation:
Notice that
is a right triangle where its hypotenuse is
. We can also see that
. For this we must use the Pythagorean Theorem.
Recall:
The Pythagorean Theorem states that if you have a right triangle, the principal square root of the sum of the squares of each leg is the length the hypotenuse.
We can see that
and ![DB = 4](https://tex.z-dn.net/?f=DB%20%3D%204)
![a = \sqrt{CD^2 +DB^2} \\ a = \sqrt{3^2 +4^2} \\ a = \sqrt{9 +16} \\ a = \sqrt{25} \\ a = 5](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%7BCD%5E2%20%2BDB%5E2%7D%20%5C%5C%20a%20%3D%20%5Csqrt%7B3%5E2%20%2B4%5E2%7D%20%5C%5C%20a%20%3D%20%5Csqrt%7B9%20%2B16%7D%20%5C%5C%20a%20%3D%20%5Csqrt%7B25%7D%20%5C%5C%20a%20%3D%205)
Answer:
1/2
Step-by-step explanation:
Okay, So you have 24x+25=6y+7
Step 1: Pull out like factors : 24x + 18 + 6y = 6 • (4x + y + 3)
Step 2: 4x+y+3 = 0
y-intercept = -3/1 = -3.00000
x-intercept = -3/4 = -0.75000
Slope = -8.000/2.000 = -4.000
And bam, you have a straight line
Answer:
∠LMN = 167°
Step-by-step explanation:
∠LMT = 23°
∠TMN = 144°
∠LMN = ∠LMT + ∠TMN
∠LMN = 23° + 144°
∠LMN = 167°
That's called <span>standard deviation.
Hope this helps !
