Answer:

D) 67.4°

Step-by-step explanation:

by observation, and noting that triangle PQR is a right triangle

sin R = opposite length / hypotenuse

in our case, the hypotenuse is PR = 13 and the length opposite form R is QP = 12

hence

sin R = opposite length / hypotenuse

sin R = 12/13

R = sin⁻¹ (12/13) = 67.4⁰

The width of a rectangle is one more than twice its length. If the rectangle's perimeter is 44 cm, then its length is ____ cm. T

Alenkasestr [34]

The length of rectangle is 7 cm.

Step-by-step explanation:

Given,

Perimeter of rectangle = 44 cm

Length = l

Width = 2l + 1

Perimeter = 2(Length + Width)

$44=2(l+2l+1)\\44=2(3l+1)\\44=6l+2\\44-2=6l\\42=6l\\6l=42$

Dividing both sides by 6

$\frac{6l}{6}=\frac{42}{6}\\l=7$

The length of rectangle is 7 cm.
