In the figure, angle e measures 30°, angle f measures 57°, and angle b measures 27°. what is the measurement of angle a?

∠A = 66°

Step-by-step explanation:

In the figure,

∠E = 30° , ∠F = 57°

In ΔEFD

Angle sum property: Sum of all three angles of a triangle is 180°

∠E + ∠F + ∠D = 180°     (Angle sum property of a triangle)

30° + 57° + ∠D = 180°

                  ∠D = 180° - 30° - 57°

                  ∠D = 93°

In ΔABC

Exterior angle property: Sum of two opposite interior angle of a triangle is equal to exterior angle.

∠A + ∠B = ∠D        (Exterior angle property of a triangle)

∠A + 27° = 93°

        ∠A = 93° - 27°

        ∠A = 66°

Hence, The measure of angle A is 66°

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.
