Question

the measure of angle abd is 40°. the measure of angle dbc is 35°. the measure of angle abc is x°. find the value of x. x =

Explanation:

Step1: Identify angle - addition relationship

We know that $\angle ABC=\angle ABD+\angle DBC$.

Step2: Substitute given angle - measures

Substitute $\angle ABD = 40^{\circ}$ and $\angle DBC=35^{\circ}$ into the equation. So $x = 40 + 35$.

Step3: Calculate the value of $x$

$x=75$.

Answer:

$75$
