Question

1. given ∠dba and ∠dbc are complementary angles, please write and use an equation to find the value of x and the measure of ∠dbc. equation: x = m∠dbc =

Explanation:

Step1: Recall complementary - angle property

$67^{\circ}+x^{\circ}=90^{\circ}$

Step2: Solve for x

$x = 90 - 67$
$x = 23$

Step3: Find measure of ∠DBC

$m\angle DBC=x^{\circ}=23^{\circ}$

Answer:

Equation: $67 + x=90$
$x = 23$
$m\angle DBC = 23^{\circ}$
