Before beginning trigonometry, you need be comfortable with algebra and geometry. You should be comfortable handling algebraic expressions and solving problems after studying algebra. You should know about similar triangles, the Pythagorean theorem, and a few other things from geometry, but not much else. Students can use trigonometry to calculate the precise angle of a triangle's sides, the distance between distinct points on a triangle, and other information that is useful in a number of situations. Trigonometry is an essential component of ICSE Class 10 Mathematics since it combines memorization, conceptual knowledge, and problem-solving abilities. Because many of the earth's natural formations resemble triangles, it aids children in their comprehension of the globe.

Hope this helps

Answer:

-You should already be familiar with algebra and geometry before learning trigonometry. From algebra, you should be comfortable with manipulating algebraic expressions and solving equations. From geometry, you should know about similar triangles, the Pythagorean theorem, and a few other things, but not a great deal.

-Measure the lengths of the sides of sets of similar right angled triangles and find the ratio of sides.

-Investigate the relationship between these ratios and the angle size.

-Use calculators or tables to find the sine, cosine and tangent of angles.

A small furniture company manufac- tures sofas and recliners. Each sofa requires 8 hours of labor and $180 in materials, while a
Bad White [126]

Answer:

30 and 20 respectively

Step-by-step explanation:

Let the number of sofas to be built be s and the number of recliners be r.

For the time part, we have the following equation:

8s + 6r = 340

For the money part:

180s + 105r = 6750

Now let’s solve these equations simultaneously.

Let’s change the form of the second equation:

180s + 17.5(6r) = 6750

From the first equation, 6r = 340 - 8s

Insert this into the third equation

180s + 17.5(340-8s) = 6750

180s + 5950 - 140s = 6750

40s = 6750 - 5950

40s = 800

s = 20

Substitute the value into the first equation

8(20) + 6r = 340

6r + 160 = 340

6r = 180

r = 30

Find the area of the region (in square units) exact number
Margaret [11]

The area of the region = area of the two rectangles = 64 units².

<h3>How to Find the Area of Rectangles?</h3>

A rectangle has a length and a width, and its area can be calculated using the formula below:

area of rectangle = (length)(width).

The region shown is composed of two rectangles. To find the area of the region, calculate the area of each of the rectangles in the image given.

Area of rectangle 1 = (length)(width)

Length = 12 units

Width = 4 units

Area of rectangle 1 = (12)(4)

Area of rectangle 1 = 48 units²

Area of rectangle 2 = (length)(width)

Length = 4 units

Width = 4 units

Area of rectangle 2 = (4)(4)

Area of rectangle 2 = 16 units²

The area of the region = area of the two rectangles = 48 + 16 = 64 units²
