it would be BC because you are basically taking the angle and drawing an arrow to the opposite side. another trick would be choosing an answer choice without the letter in it. also you didn't put what shape so I assumed it was a triangle

The basketball game lasted 1 hour and 40 minutes. If the game started at 7:30 p.m., what time did it end?

(Answer:_:__)​

Answers

Answer:

9:10pm

Step-by-step explanation:

the game ended at 9:10pm

Answer:

21:10 (24-hour clock) or 9:10 ( 12-hour clock)

Step-by-step explanation:

Two ways it can be solved:

Starting time: 7:30

Game lasted- 1 hour and 40 minutes

Ending time-?

7:30 is converted to 24 hrs timing clock:

∴ hr  I min

   7   :  30 pm

+ 12  :  00

___________

=  19  :  30

Then, hr  I min

        19  :   30

    +   1    :   40

______________

=       20  :   70

    +    1   : - 60

______________

=       21   :  10

So it ended at 21:10 (24-hour clock) or 9:10 ( 12-hour clock).

or you can just add up :

  hr  I min

   7  : 30pm

+ 1   :  40

________

=  8 :  70

 + 1  : - 60

_________

=  9  : 10 pm

In the coordinate plane, point C lies on segment AB. If the ratio of the length of segment AC to the length of segment CB is 3:1, find the x-coordinate of C given the coordinates of A(3, 12) and B (14, 17).


Question 14 options:


A. 11.25



B. 6



C. 5.75



D. 12

Answers

Answer:

A. 11.25

Step-by-step explanation:

If point C(x, y) divides line segment AB with end points at A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2\\[/tex]) in the ratio on n:m, then the coordinates of point C is:

[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]

Given that segment AB is divided by point C in the ratio of 3:1. Given A(3, 12) and B (14, 17). Let coordinate of C be (x, y), hence:

[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1\\\\x=\frac{3}{3+1}(14-3)+3=\frac{3}{4}(11)+3=11.25 \\\\\\y=\frac{n}{n+m}(y_2-y_1)+y_1\\\\y=\frac{3}{3+1}(17-12)+12=\frac{3}{4}(5)+12=15.75[/tex]

Therefore, the coordinate of point C = (11.25, 15.75)

The x coordinate of point C is 11.25

Answer: I think it is B

Step-by-step explanation:

Help plz. If u know the answer also show work for how you got it plz. Thanks!

Answers

The answer is 37. You use Pythagorean theorem so you get 5 squared + b squared= 13 squared. You’d get 25+ b squared= 169. You subtract 25 from 169 and you get b squared equals 144. You square root both the b and 144 and You would get 12 for that side. Then you do Pythagorean theorem again. You do 12 squared+ 35 squared= c squared. This would turn into 144+1,225= c squared this simplifies to 1,369= c squared. You square root both sides and you get your final answer 37

Answer:

The triangle EFG can be constructed with the following specifications: [tex]EF = 8\,cm[/tex], [tex]FG = 7\,cm[/tex], [tex]EG = 12\,cm[/tex], [tex]E \approx 34.093^{\circ}[/tex], [tex]F \approx 106.068^{\circ}[/tex], [tex]G \approx 39.838^{\circ}[/tex].

Step-by-step explanation:

A triangle is formed by either knowing the lengths of its three sides or knowing two angles and the length of a side or knowing a angle and the lengths of two sides. By Geometry, we know that sum of internal angles in triangles equals 180°. In order to construct this triangle, we need to know the measures of angles E, F and G by means of the Law of Cosine:

Angle E

[tex]E = \cos^{-1}\left[\frac{(7\,cm)^{2}-(12\,cm)^{2}-(8\,cm)^{2}}{-2\cdot (12\,cm)\cdot (8\,cm)} \right][/tex]

[tex]E \approx 34.093^{\circ}[/tex]

Angle F

[tex]F = \cos^{-1}\left[\frac{(12\,cm)^{2} - (8\,cm)^{2} - (7\,cm)^{2}}{-2\cdot (8\,cm)\cdot (7\,cm)} \right][/tex]

[tex]F \approx 106.068^{\circ}[/tex]

Angle G

[tex]G = \cos^{-1}\left[\frac{(8\,cm)^{2}-(12\,cm)^{2}-(7\,cm)^{2}}{-2\cdot (12\,cm)\cdot (7\,cm)} \right][/tex]

[tex]G \approx 39.838^{\circ}[/tex]

The triangle EFG can be constructed with the following specifications: [tex]EF = 8\,cm[/tex], [tex]FG = 7\,cm[/tex], [tex]EG = 12\,cm[/tex], [tex]E \approx 34.093^{\circ}[/tex], [tex]F \approx 106.068^{\circ}[/tex], [tex]G \approx 39.838^{\circ}[/tex].
