The angle shown is in standard position. select the possible measures of the angle. –450° –360° –270° –90° 90° 270° 360° 450°

See the figure below. so in an standard position, the vertex of the angle called (B) is on the origin (0, 0) of the x and y axis. Therefore, one side of the angle is always fixed along the positive x-axis, namely, going to the right along the axis in the 3 o'clock direction (see line BC in the figure). This is called the initial side of the angle.The other side of the angle is called the terminal side.

So, in the subsequent figures you can see each angle drawn. Then, the angles that match the figure above are the measures of the angle. That is:

-450°

-90°

270°

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
