AB is tangent to circle O find the length of radius r to the nearest tenth please answer ASAP will mark as brainlist
Answer:
7.62
Step-by-step explanation:
Using Phythagoras' theorem...
Hyp^2 = a^2 + b^2
that is:
8^2 = 11^2 + r^2
64 = 121 + r^2
64-121 = r^2
58 = r^2
therefore r = sqrt of 58
NB: Not sure but there you go.
Answer:
r ≈ 3.6
Step-by-step explanation:
∠ OAB is right ( angle between tangent and radius at point of contact )
then Δ OAB is a right triangleΔ
using Pythagoras' identity in the right triangle
with hypotenuse OB = r + 8 , then
OB² = OA² + AB² , that is
(r + 8)² = r² + 11²
r² + 16r + 64 = r² + 121 ( subtract r² from both sides )
16r + 64 = 121 ( subtract 64 from both sides )
16r = 57 ( divide both sides by 16 )
r = [tex]\frac{57}{16}[/tex] ≈ 3.6 ( to the nearest tenth )

Which of the following estimates at a 95% confidence level most likely comes form a small sample?
OptionAStep-by-step explanation:95% confidence interval is obtained using the following formulaCOnfidence interval lower bound = mean - critical value * sigma/sq rt nand upper bound = mean + critical value*sigma/sq rt nThus margin of error = critical value*sigma/rt nvaries indirectly as n provided others are remaining the same.Hence lower sample indicates higher margin of errorOut of 4 options given we find that 1 option has maximum margin of error as 21%Hence option. A is most likely coming from a small sample.

Find the value of x. Segments that appear to be tangent are tangent. Round your answer to the nearest tenth. Do not include "x=" in your answer.
The square of the hypotenuse is equal to the sum of the square of other two sides. The value of x from the given diagram to the nearest tenth is 11.2
Pythaogram theoremAccording to the theorem, the square of the hypotenuse is equal to the sum of the square of other two sides.
From the diagram
hypotenuse = 5.6 + 8.4 = 14
Other sides are x and 8.4
According to the theorem:
14^2 = x^2 + 8.4^2
x^2 = 14^2 - 8.4^2
Simplify
x^2 = 196 - 70.56
x^2 = 125.44
x = 11.2
Hence the value of x from the given diagram to the nearest tenth is 11.2

What is the sum of the exterior angles of the equilateral triangle ∠M + ∠R + ∠X? Explain your reasoning
N = 60
M = 120
Answer:
360
Step-by-step explanation:
The inside corners of an equilater trinagle measure 60 degrees
Besides: ∠M + ∠N = 180 because supplementary angles
∠M + 60 = 180 --> ∠M = 120
Same reasoning for the pair ∠Q , ∠R and for the pair ∠X , ∠top insideangle
Hence ∠R = 120 and ∠X = 120
Therefore, the sum of the exterior angles is
∠M + ∠R + ∠X = 360

You were on the right track. Here are two ways to go about it.
• By definition of conditional probability,
Pr[A | B] = Pr[A and B] / Pr[B]
Out of the total 100 participants in the survey, there are 18 people that both have a positive attitude and are over 35, so
Pr[positive and over 35] = 18/100
Out of the 100 pariticipants, 40 are over 35, so
Pr[over 35] = 40/100
Then the conditional probability you want is (18/100) / (40/100) = 18/40 = 9/20.
• There are 40 people over 35 in the survey. You want the probability that someone randomly chosen from this group has a positive attitude, of which there are 18. Hence the probability is 18/40 = 9/20.

How many protons, neutrons, and electrons are found in a neutral atom of carbon-13?
Since both are neutral, we know that each has 6 electrons as well. The sum of protons plus neutrons equals the mass number 12 in 12-C, so carbon-12 has 12 – 6 protons = 6 neutrons. The sum of protons plus neutrons equals the mass number 13 in 13-C, so carbon-13 has 13 - 6 protons = 7 neutrons.

Which argument explains why the measure of ∠3 is also 65°?
In triangle ABC, m∠A=23° and m∠B=33°. What is m∠C?
The measure of angle C is 122 degrees.
We have given that,
In triangle ABC, m∠A=23° and m∠B=33°
We have to determine the remaining angle of the triangle.
What is the sum of the angle of the triangle?
The sum of the angles in a triangle is 180 degrees.
Therefore we get
angle A+ angle B+ angle C= 180 degrees
23+33+angle C=180
angle C=180-56
angle C=122
Therefore the measure of angle C is 122 degrees.

SBC is an isosceles triangle with main vertex S.
→ Let D be the symmetric of B with respect to C and A the symmetric of C with respect to B.
1) Compare AB and CD
2) Compare the angles SBA et SCD.
3) Deduce that the triangles SBA and SCD are congruent.
4) What is the nature of the SAD triangle?
Help me if u help me u get points I’m poor help me I don’t have much time :(
Answer + Step-by-step explanation:
1) D be the symmetric of B with respect to C then CD = BC
A the symmetric of C with respect to B then AB = BC
We obtain :
CD = BC
AB = BC
Then AB = CD
2) m∠SBA = 180 - SBC = 180 - SCB = m∠SCD
3) we have :
BA = CD
BS = CS
m∠SBA = m∠SCD
Then
the triangles SBA and SCD are congruent
4)
the triangles SBA and SCD are congruent Then SA = SD
Therefore SAD is an isosceles triangle.
