Answer:
Option D is correct.
cosecant of an angle R is,
Step-by-step explanation:
In the given triangle DRW is right triangle.
To find the cosecant of angle R;
In a right angled triangle, the cosecant of an angle defined as
the length of hypotenuse side divided by the length of the side opposite the angle.
The abbreviation for cosecant is csc
i,e
In the given triangle DRW as show in figure;
hypotenuse sides = 13 units and
Opposite side to an angle R is 12 units;
then;
Therefore, the cosecant of an angle R is,
Answer:
y = 5
Step-by-step explanation:
Since the lines are parallel, same side interior angles are supplementary.
That allows us to solve for x.
7x + 17 + 5x - 5 = 180
12x = 168
x = 14
The angles 23yand 5x - 5 are supplementary, so the sum of the measures equals 180°.
23y + 5x - 5 = 180
We already know that x = 14.
23y + 5(14) - 5 = 180
23y = 115
y = 5
Answer:
%20
Step-by-step explanation:
formula: %/100 x part/whole
%/100 x 13/65 = 1300/65 = 20
Answer:
Step-by-step explanation:
1. You have a ladder that is 10 feet tall and you place it on the ground 6 feet away from your house, which you plan to paint. How far up will the ladder reach? (Ans: 8 feet)
2. I think drawing a diagram of this is pretty self-explanitory. Just remember to lable the ladder as 10 feet, the ground as 6 feet, and the house as 8 feet.
3. There wasn't really an equation in the question, but if you draw a triangle you'll need to solve for the third side. It would be 8 feet, but if you consider the pythagoran therom:
100ft(c^2, the hypotenuse, or the ladder)- 36 ft(a^2, or the ground)= 64, the square root of 64 would give you 8. You can write it out symbolically, but I'm typing and there's not much I can do on here.
