Will give brainliest pl. Which statement justifies why ∠EBC measures 90°? Given: angles ABD and DBC are complementary Point B is on line AE between points A and E, point B is on line FD between points F and D, ray BC intersects with line AE at point B, line FD intersects with line AE at point B, the measure of angle ABD is 50 degrees, and it is given that angles ABD and DBC are complementary. A linear pair is two adjacent, supplementary angles. The sum of the measures of complementary angles is 90 degrees. If two angles are vertical angles, then they are congruent. Alternate interior angles are congruent.

he sum of the measures of two complementary angles is 90 degrees

Step-by-step explanation:

we know that

If two angles are complementary, then their sum is equal to 90 degrees

In this problem we have that

m∠ABD and m∠DBC are complementary

so

m∠ABD + m∠DBC=90° > by complementary angles

and

(m∠ABD + m∠DBC)+m∠EBC=180° > by a linear pair

Find the measure of angle EBC

substitute the given values

(90°)+m∠EBC=180°

∠EBC=180°-90°=90°

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
