In triangle ABC angle c = 180-78-40 = 62 degrees
For the triangles to be congruent angle z must equal angle C
Solve for x:
2x + 8 = 62
Subtract 8 from both sides:
2x = 54
Divide both sides by 2:
X = 27
Now we k ow x has to equal 27 to be concurrent so we can answer the 3 questions.
A. False
B. True
C. True

Answer:
The sample size 'n' = 384
Step-by-step explanation:
<u>Step(i)</u>:-
Given data the margin of error = 0.05
The margin of error of the estimation of a population proportion is determined by

<u><em>Step(ii)</em></u>:-
In data not given sample proportion 'p' but
we know that 

cross multiplication, we get
0.05 ×√n = 0.98

<em>squaring on both sides, we get</em>
<em>n = 384.16≅ 384</em>
<u><em>Final answer</em></u><em>:-</em>
<em>The sample size 'n' = 384</em>
Answer:52.33 m/s
Step-by-step explanation:
Given
Speed of car 
Speed of truck 
Distance traveled by car in 1 hr is 33 mi
Therefore after 11 am distance of car and truck from Junction in time t is
Car 
truck 
Let D be the distance between them
------------1
at 


To get how fast distance between them is increasing differentiate 1 we get
