The angles 1 and 2 are right angles.

As stated in the question line l is perpendicular to line m and perpendicular lines create right angles

Hope this helps :)

Perimeter of the ΔJKL is 48 cm

Solution:

Given $\triangle \mathrm{RST} \sim \Delta \mathrm{JKL}$ .

RS = 8 cm and JK = 12 cm

Perimeter of $\triangle R S T$ = 32 cm

Let us find the perimeter of $\Delta J K L$ .

<u>Property of similarity triangles:</u>

If two triangles are similar, then the ratio of their perimeters is equal to the ratio of their corresponding sides.

$$\frac{\text{Perimeter of}\ \triangle RST }{{\text{Perimeter of}\ \triangle JKL}} =\frac{RS}{JK}$

$$\Rightarrow\frac{32 }{{\text{Perimeter of}\ \triangle JKL}} =\frac{8}{12}$

Do cross multiplication.

$$\Rightarrow 32\times 12 ={8}\times {\text{Perimeter of}\ \triangle JKL}$

$$\Rightarrow 384 ={8}\times {\text{Perimeter of}\ \triangle JKL}$

Divide both sides of the equation by 8.

$$\Rightarrow 48 = {\text{Perimeter of}\ \triangle JKL}$

Hence perimeter of the ΔJKL is 48 cm.

Lydia bought a shirt at 20% off its retail price of $40. She paid 5% tax on the price after the discount. How much did Lydia pay

mestny [16]

Retail Price= $40

Price after 20% discount

20/100 x 40 = $8

40-8= $32 after discount

tax paid on $32 shirt = 5/100 x32 = $1.6

she paid $32+$1.6= $33.6
