What is the interior angle bisector theorem?The interior angle bisector theorem states that in a triangle the angle bisector of an angle divides the opposite side to the angle in the ratio of the remaining two sides.
In ΔABC m∠A = 28° and the ratio is taken for the sides which is opposite to the given angle BC and the side which not base AB.
Given the ratio AB/BC.
∴ In ΔBCD in which m∠B is also 28° we have to take the same sides opposite side is DC and the side which is not the base BC.
So, in the triangles ABC and ABD The ratio which has the same value as AB/BC is BC/DC.

I remember doing the last question.
If you recall, x = 29
Just plug 29 into x for each angle
A = 3(29) = 87
B = 2(29) + 1 = 59
C = 29 + 5 = 34
Answer:
The value of angle C is 34°
Step-by-step explanation:
2x+1°+x+5°+3x° = 180° { the sum of angle of triangle is 180°}
or, 6x + 6° = 180°
or, 6x = 180° - 6°
or, x = 174°/6
or, x = 29°
now,
value of angle C = x+5°
= 29°+5°
= 34°

Answers
2-78-45=33 33-12=21
I have 21 $ left
3 9/3 =3 3 multiply by 5 = 15
15 tigers there
Answer:
1.) $54
2.) $21 left
3.) 15 tigers
Step-by-step explanation:
1.) If the original price of an item was $60, and it was reduced by 10%, that means it is now being sold at 90% of its original value.
To find out the new price, simply take the original value and multiply it by 90% (as a decimal).
60*.90=54
So the new price is $54
2.) This is simple subtraction. If you spend $45 on some CDs and $12 on a t-shirt, you spent a total of $57. Subtract $57 from your total of $78.
78-57=21
You are left with $21
3.) Ratios are all about multiplication. If the ratio of lions to tigers is 3:5, that means that the number of lions is going to be any factor of 3, as long as it corresponds to the same factor of 5 for the tigers.
For example, if there are 9 lions, there must be 15 tigers.
3*3=9
5*3=15
There are 15 tigers

The number of hot dogs Ryan can eat varies directly with the amount of time he spends eating. If Ryan can eat 14 hot dogs in 6 minutes, how many hot dogs can he eat in 15 minutes? HELPPPPPPPPPPP
Answers
Answer:
35
Step-by-step explanation:
Let h represent the number of hot dogs Ryan eats in 15 minutes. Since the rates are the same, we have ...
dogs/minutes = h/15 = 14/6
Multiplying by 15 gives us ...
h = (15·14)/6 = 35
Ryan can eat 35 hot dogs in 15 minutes.
