Find the measurement of angle π·π΅πΆ.

Here we have point π·, π΅, and πΆ. This is angle π·π΅πΆ. There are two angles in the given figure on a straight line. Angles on a straight line total 180 degrees. This means that angle π·π΅πΆ plus 35 degrees equals 180 degrees. So we can use the inverse to help find the answer. We need to subtract 35 from 180 degrees to give us the measure of angle π·π΅πΆ. 180 degrees take away 30 degrees gives us 150 degrees. Weβve subtracted the 30 from 35. Now we just need to subtract the five. 150 subtract five is 145.

Angle π·π΅πΆ measures 145 degrees.
