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

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

                                                                                       answers

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
