List the angles of ∆ abc from smallest to largest. Ab = 20, bc = 12, ca = 10.

Answers

Answer 1

The angle of the triangle ABC from smallest to largest are approximately 22°, 27° and 131°.

The sides of the triangle are as follows;

AB = 20

BC = 12

AC = 10

Let's find ∠A using cosine rule,

a² = b² + c² - 2bc cos A

cos A = b² + c² - a² / 2bc

Therefore,

cos A = 10² + 20² - 12²  / 2 × 10 × 20

cos A = 100 + 400 - 144 / 400

cos A = 356 / 400

cos A = 0.89

A = cos⁻¹ 0.89

A = 27.1267531173

∠A ≈ 27°

Using sine rule let's find ∠B

12 / sin 27 = 10 / sin B

cross multiply

12 sin B = 10 sin 27

sin B = 10 sin 27 / 12

sin B = 10 × 0.45399049974  / 12

sin B = 4.5399049974  / 12

B = sin⁻¹ 0.37832541645

B = 22.2299936087

∠B = 22°

Using sum of triangle theorem let's find ∠C

∠C = 180 - 27 - 22

∠C = 131°

The angles from smallest to largest are approximately 22°, 27° and 131°.

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's assertion correct?.

Answers

No product results in -1, hence δlmn is NOT a right triangle showing that  lydia's assertion is incorrect

Perpendicular lines

In order to determine whether triangle lmn  is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

[tex]m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1[/tex]

For the slope of ln:

[tex]m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\[/tex]

For the slope of mn:

[tex]m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\[/tex]

If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

[tex]m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2[/tex]

Since no product results in -1, hence δlmn is NOT a right triangle showing that  Lydia's assertion is incorrect
