U should know the area of rectangle is w*l
if we increase it by double or times 2 its area will be
A=2w*2wl
A=4wl
area would be 4 times of original one
Now u can get the answer

URGENT EXPLANATION AND SOLVING

Alex787 [66]

$\cfrac{a}{\sin(a)} = \cfrac{b}{\sin(b)} 
$

$\cfrac{31}{\sin(42)} = \cfrac{37}{\sin(x)} 
$

$31\sin(x) = 37 \sin(42)$

$\sin(x) = \cfrac{37 \sin(42) }{31}$

$x = \sin^{-1}(\cfrac{37 \sin(42) }{31} )$

$x = 53 \textdegree$

Answer: 53°

Find the approximate area of the triangle y x> O 30 square units O 15 square units 21 square units 45 square units

Fiesta28 [93]

Answer:

Step-by-step explanation:

a right triangle is half of a rectangle and the area of a rectangle is

area of rectangle = length × width

Area of a triangle is one half times the length times the width

area of triangle = 1/2 × length × width

in this case

length is the number of the y units

width is the number of x axis unit

area of triangle = 1/2 × length × width

area of triangle = 1/2 × (y units) × (x units) you need to count and insert

the number of units into the

equation

area of triangle = 1/2 × (??? y units ) × (??? x units ) do the math yourself

and see if you get one of
