What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

In a triangle;

⇒ ∠ A = 27°, ∠ B = x

⇒ Side (a) = 11, Side (b) = 15

Now,

The sine rule of triangle is,

⇒ sin A / a = sin B / b = sin C / c

Substitute all the values, we get;

⇒ sin 27° / 11 = sin x / 15

⇒ 0.45 / 11 = sin x / 15

⇒ sin x = 0.45 × 15 / 11

⇒ sin x = 0.61

⇒ x = sin ⁻¹ 0.61

⇒ x = 37.6°

Thus, The value of x = 37.6°

For [K] > 0, the dilated image will be larger than the original image.

What is triangle?

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a triangle ABC which is taken to triangle A'B'C' by a dilation.

After dilation by scale factor [K], the length of the sides of triangles change by the following rule -

A'B' = K(AB)

B'C' = K(BC)

C'A' = K(CA)

If K < 0, the image will shrink. If K > 0, the image will enlarge

Therefore, for [K] > 0, the dilated image will be larger than the orginal image.

Answer:

BC=53.68

Step-by-step explanation:

Use tangent since you are finding the opposite side and given the adjacent side.

tan(54)=BC/39

BC=53.68

Answer:

C

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan54° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{39}[/tex] ( multiply both sides by 39 )

39 × tan54° = BC, then

BC ≈ 53.68 ( to 2 dec. places ) → C

Answers

Answer:

A

Step-by-step explanation:

Its a right angle, so you have to use trigonometry.

To find x , you use sin60° = opposite/hypotenuse

opposite = x and hypotenuse = 5 . So,

sin60°= x/ 5

5sin60° = x

put the value into your calculator you ' ll get:

[tex] x = \frac{5 \sqrt{3} }{2} [/tex]

To find y, cos60°= adjacent/hypotenuse

adjacent= y and hypotenuse = 5. So,

cos60°= y/5

5cos60°=y

[tex]y = \frac{5}{2} [/tex]

Find the missing side in each triangle using any method.

Answers

I used the Pythagorean theorem for both triangles.Small Triangle) The missing side is equal to 13We have to solve the hypotenuse here:5² + 12² = ?(5 x 5) + (12 x 12) = 169The square root of 169 is 13Big Triangle) The missing side is equal to 24We have to solve for a leg here:26² - 10² = ?(26 x 26) - (10 x 10) = 576The square root of 576 is 24Please let me know if I am wrong.

The missing side lengths of the right triangles are AC = 13 and DE = 24.

What is the Pythagorean theorem?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given the two right triangles.

The hypotenuse of the first right triangle is given by:
AC² = 5² + 12²

AC² = 25 + 144

AC² = 169

AC = 13

The length of the leg in the second triangle is given by:

DE² = 26² - 10²

DE² = 676 - 100

DE² = 576

DE = 24

Hence, the missing side lengths of the right triangles are AC = 13 and

DE = 24.

Answers

Answer:

x = 12°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

So,

39° + 53° + 4° + 7x = 180°

Add all the numbers on the left up.

96° + 7x = 180°

Subtract 96 from both sides.

7x = 84°

x = 12°

Hope this helps!

Answer: x= 12

Step-by-step explanation:

Triangle angle sum theorem says that the interior angles of a triangle sum to 180 degrees. Set the sum of all of these angles equal to 180 to solve. 39+53+ (4+7x) = 180. Combine like terms. 96 +7x = 180. Subtract 96 from both sides. 7x = 84. Divide both sides by 7. X = 12
