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 linesIn 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

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