In ∆ABC, AC = 15 centimeters, m B = 68°, and m C = 24°. What is BC to two decimal places?6.58 centimeters
9.88 centimeters
13.57 centimeters
16.17 centimeters
19.25 centimeters

Answers

Answer 1

Answer: I dont know which math you are in but you can use the law of sins. (A/sin(a))=(B/sin(b)) where the capital letters are the sides (in this case you would put AC or whatever side length it is) and the lower case letters are the measures on the angles.
that may have been confusing but look up the laws of sines and cosine because you'll need to learn them and it's very helpful.
15/sin68 = x/sin88 x is the side BC and to get angle A, do 180-68-24
so x= sin88 (15/sin68)
so the answer to this question would be 16.17 cm

Answer 2

Answer:

Answer:

16.17 cm would be the answer

State a true conclusion.1) If a triangle has a right angle, then the triangle is a right triangle.
2) Triangle ABC is not a right triangle.

Conclusion:

Answers

Answer:

The conclusion is that the triangle ABC doesn't have any right angles because all angles are less than 90°

Final answer:

Given the statements that 'if a triangle has a right angle, then it's a right triangle' and that 'Triangle ABC is not a right triangle', we can conclude that 'Triangle ABC does not have a right angle'.

Explanation:

The given statements are:

If a triangle has a right angle, then the triangle is a right triangle.
Triangle ABC is not a right triangle.

From these statements, the true conclusion that can be drawn is: Triangle ABC does not have a right angle.

This conclusion is derived from the logical sequence of the given statements. In simple terms, statement 1 tells us that having a right angle defines a right triangle. Then, in statement 2, we are told that Triangle ABC is not a right triangle, which, based on statement 1, allows us to conclude that Triangle ABC does not have a right angle.

Angela had 2 cups of flour. She used 1 1/4 cups when making muffins. Angela says she has 3/4 cup of flour left. Is Angela's answer reasonable?

Answers

Angela's answer is reasonable because if you had 2, and you subtracted 1 and 1/4, you would be left with 3/4 left. You can easily check your work by doing
3/4 + 1 1/4 = 2

A writing workshop enrolls novelists and poets in a ratio of 5:3. There are 24 people at the workshop. How many novelists are there? How many poets are there? Write a system of equations to model each situation. Solve by any method.

Answers

There are 15 novelists and 9 artists. I did it in my head though, but I'll show what I did.
5+3=8
8x=24
X=3
3x5=15 novelists
3x3=9 artists

Novelists 5= 15
Poets 3= 9
Total 8= 24

Step-by-step explanation:

A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?15 in3
20 in3
25 in3
30 in3

Answers

The answer is 15 in³.

The volume of the cone is:
$V_1= \pi r_1 ^(2) (h_1)/(3) = ( \pi r_1^(2) h_1)/(3)$
where:
V₁ - the volume of the cone
r₁ - the radius of the cone
h₁ - the height of the cone

The volume of the cylinder is:
$V_2= \pi r_2h_2^(2)$
where:
V₂ - the volume of the cone
r₂ - the radius of the cone
h₂ - the height of the cone

Since the cone fits exactly inside of the cylinder, they have the same radius and the height:
r₁ = r₂
h₁ = h₂

Also:
V₁ = 5

Now, let's write two volume formulas together:
$V_1= ( \pi r^(2) h)/(3)$
$V_2= \pi rh^(2)$

We can include V₂ into V₁:
$V_1= (V_2)/(3)$

⇒ $V_2=3*V_1$
$V_2=3*5 in^(3)$
$V_2=15 in^(3)$

Solve the equation.
