Answer:
7.75 cm
Step-by-step explanation:
Let a circle having centre O and AB is a tangent of the circle and OB is the radius of the circle = 2 cm. And join AO such that AO = 8 cm.
Answer:
[μ-error, μ + error]
[14000- 3000, 14000 + 3000]
Step-by-step explanation:
We write it how an interval, where the center of the interval is the mean, thus
[μ-error, μ + error]
First we calculate the mean
μ = (11000+17000)/2
μ = $14000
And the error is the absolute value of the difference between the mean an either extreme values
error = |14000 -17000| = |14000 - 11000| = 3000
Then
[14000- 3000, 14000 + 3000]
Answer:
Choose one:
ray LG
ray LI
ray LJ
Step-by-step explanation:
There are three possible correct answers in this problem.
You only need one of them, but I will give you all three, and you choose the one you prefer.
Answer 1.
Ray LG is an angle bisector.
m<KLH = 120°
m<KLG + m<GLH = m<KLH
60° + m<GLH = 120°
m<GLH = 60°
Since m<KLG + m<GLH = m<KLH, and m<GLH = m<KLG, then
ray LG is the angle bisector of <KLH.
Answer: ray LG
Answer 2.
Angles KLH and HLM are a linear pair and supplementary. Their measures add to 180°. Since m<KLH = 120°, then m<HLM = 60°.
m<HLI = 30°, so m<ILM = 30°.
That makes ray LI a bisector of angle HLM.
Answer: ray LI
Answer 3.
Since ray LI bisects <HLM, and m<HLM = 60, then m<ILM = 30°.
We are given m<JLM = 15°, so m<ILJ is also 15°. That makes ray LJ an angle bisector.
Answer: ray LJ
You would want to do base x height to find the area.
20x10
That Will equal 200
Answer:
a = -21 and b = 15
Step-by-step explanation:
It is given a matrix multiplication,
<u>To find the value of a and b
</u>
It is given that,
| 6 -5 | * | -1 | = | a |
|-3 4 | | 3 | | b |
We can write,
a = (6 * -1) + (-5 * 3)
= -6 + -15
= -2
1
b = (-3 * -1) + (4 * 3)
= 3 + 12
= 215
Therefore the value of a = -21 and b = 15
