Step-by-step explanation:
you have to use the fact that the big triangle and the small triangle are similar and write the proportions
[tex]\frac{125}{10} =\frac{AB}{10}[/tex] we took half of the side because of ΔABD and ΔBD..
AB= (125*10)/10=125
is AB =125 then AC is duble AC= 2*125=250

what is the equation of the line that is perpendicular to the line y=-1/2 (X -18) and intersects the Y axis at (0, -1)
Answers
Answer:
The equation of the perpendicular line is 2 x + y + 1 =0
Step-by-step explanation:
Step(i) :-
Given equation of the line 2y = x - 18
x - 2y - 18 =0
The equation of the perpendicular line to the given line
b x - ay +k=0
-2 x - y + k =0 this line is passing through the point ( 0 , -1)
⇒ 0 -(-1) + k=0
⇒ 1+k =0
⇒ k = -1
Step(ii):-
The equation of the line is perpendicular to the line
-2x - y - 1 =0
2 x + y + 1 =0
Conclusion:-
The equation of the perpendicular line to the given line 2 x + y + 1 =0
The required equation of the line [tex]l_1[/tex] is perpendicular line [tex]l_2[/tex] is 2x + y +1 = 0
Given ,
The equation of the line [tex]l_1[/tex] is Y = [tex]-\frac{1}{2} ( X- 18 )[/tex]
We have to find ,
The equation of line which perpendicular to [tex]l_1[/tex] and intersects the Y-axis at (0, -1).
According to the question,
[tex]Y = \frac{-1}{2} (X - 18)[/tex]
2Y = -1 ( X - 18)
2Y = -X + 18
2Y + x - 18 = 0
Then , the given line is perpendicular to the line [tex]l_1[/tex] to line [tex]l_2[/tex]
b = 2 , a = 1 ,
bx - ay + k = 0
2x - 1y + k = 0
The intersection point the Y- axis ( 0 , -1 )
2(0) - 1(-1) + k = 0
0 + 1 + k = 0
k = -1
Put the value of k in equation and write the equation at Y - axis
-2x -y -1 = 0
The required line is 2x+y+1 = 0
The required equation of the line [tex]l_2[/tex] is perpendicular line [tex]l_1[/tex] is 2x + y +1 = 0 .

Statement
Truthfulness
At least one student is 23. Must be true could be true cannot be true
Some students are younger than 15. Must be true could be true cannot be true
Answers
Answer:
1) At least one (the 11th) student is 23 (years old), Must be true
2) Some students are younger than 15 Could be true
Step-by-step explanation:
1) The given parameters are;
The number of student in the class = 21
The median age of the student = 23
The age of the oldest student = 29
Therefore, given that the median age = The age of the (n + 1)/2 th student
Where;
n = The number of student in the class = 21
∴ The median age = The age of the (21 + 1)/2 th = 11 th student, when the age of the students are arranged in increasing order, therefore, we have;
At least one (the 11th) student is 23 (years old), Must be true
2) Given that there are 10 students with ages equal to or lower than the median age, and the difference between the median age and the age of the oldest student = 29 - 23 = 6 years, we have;
Some students are younger than 15 Could be true

Angle B is an acute angle in a right triangle. What is a reasonable approximation for angle B if the ratio for the opposite leg divided by the hypotenuse is 0.67?
Answers
Answer:
42.1 degrees
Step-by-step explanation:
- since we have a opposite/hypotenuse ratio, that means we used sin x = o/h
- this means, sin x = 0.67
so, x = [tex]sin^{-1[/tex](0.67) {sin inverse}
x = 42.06 degrees, i rounded it up to 42.1 but its up to you (or according to the question)
