URGENT EXPLANATION AND SOLVING

\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
