Question

unit 1 - lesson 5 exit ticket: in the diagram below, points a, b, and c are collinear. ∠abe is a right - angle and bd has been drawn. (a) name one pair of complementary angles. (b) if m∠abd = 25° what is the measure of

Explanation:

Step1: Definir ángulos complementarios

Los ángulos complementarios suman 90°. Dado que ∠ABE = 90°, los ángulos ∠ABD y ∠DBE son complementarios.

Step2: Calcular medida de ángulo

Sabemos que ∠ABD + ∠DBE=90°. Si m∠ABD = 25°, entonces m∠DBE=90° - m∠ABD.
m∠DBE = 90°-25°

Answer:

(a) ∠ABD y ∠DBE
(b) 65°
