How do you find the cosine of a triangle?
the cosine of an angle in a right triangle equals the adjacent side divided by the hypotenuse: Also, cos A = sin B = b/c.
The cosine formula to find the side of the triangle is given by: c = √[a2 + b2 – 2ab cos C] Where a,b and c are the sides of the triangle.
Pythagoras Theorem is a generalization of the Law of Cosine.
The law of cosine can be applied in any triangle.

By intersecting secants theorem:
[tex]9(2x - 17 + 9) = 8(8 + 10) \\ \\ 9(2x - 8) = 8 \times 18 \\ \\ 2x - 8 = \frac{144}{9} \\ \\ 2x - 8 = 16 \\ \\ 2x = 16 + 8 \\ \\ 2x = 24 \\ \\ x = \frac{24}{2} \\ \\ x = 12[/tex]
CE = 9 + (2x - 17)
CE = 9 + (2*12 - 17)
CE = 9 + (24 - 17)
CE = 33 - 17
CE =16

Intersecting Secant (Exterior)
Find X =
Answers
Answer: x = 13
Step-by-step explanation: the equation to solve this is:
4 × (4 + 8) = 3 × (3 + x)
so we solve the first half of that:
4 × (4 + 8)
4 × 12
48
now we have:
48 = 3 × (3 + x)
so we switch the sides to make it easier and solve
3 × (3 + x) = 48
divide both sides by 3
3 × (3 + x) ÷ 3 = 48 ÷ 3
and get
3 + x = 16
now subtract 3 from both sides
3 + x = 16
-3 -3
and finally we get
x = 13

A triangular prism has a height of 9 meters and a triangular base with the following dimensions.
What is the volume of the prism?
- 420 m^3
- 288 m^3
- 324 m^3
- 432 m^3
Answers
Answer:
V = 432 m³
Step-by-step explanation:
The volume (V) of a prism is calculated as
V = Ah ( A is the area of the base and h the height )
A = [tex]\frac{1}{2}[/tex] bh ( area of triangular base, with b the base, h the perpendicular height)
Here b = 16 and h = 6 , then
A = [tex]\frac{1}{2}[/tex] × 16 × 6 = 8 × 6 = 48 m²
Then
V = 48 × 9 = 432 m³

Find the area of the composite figure. Show your work. What is the area of the figure?
Answers
Answer:
46 units²
Step-by-step explanation:
The figure can be decomposed into 2 triangles and a rectangle.
Area of rectangle = L*W
W = 4
L = 8
Area = 32 units²
Area of triangle 1:
Area = ½(b*h)
b = 3
h = 4
Area = ½*3*4
Area = 6 in.
Area of triangle 2:
b = 4
h = 4
Area = ½*4*4
Area = 8 units
✅Area of the figure = 32 + 6 + 8
= 46 units²

the table shows the costs of different size jars of peanut butter. Which of the jars have the lowest unit rate?
Answers
Answer:
Step-by-step explanation:
Option C) 25-oz jar has the lowest unit rate
What is the unit rate?Unit rate is the ratio of two different units, with the denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc
Given here the cost of a 12 oz jar is $3
so the unit rate of a 12 oz jar is = 12/3
= 4
similarly, the unit rates of all the jars from the given table are
18 oz jar = 18/4.40
= $4.09
25 oz-jar = 25/6.75
= $3.703
32 oz jar = 32/8.25
= $3.87
Hence the jar with the lowest unit rate is the 25 oz jar
