Use the image to answer the question.

An illustration shows five rays with points near the arrows labeled A, B, C, D, and E in a counterclockwise direction, emerging from a common point labeled O. The points A, O, and E fall on a straight line. All the four angles are marked but unlabeled.

Question
Use the image to answer the question.

An illustration shows three rays passing through three points from a common origin point at upper B. Point upper C is to the horizontal left of upper B. A ray from upper B joins upper C with an arrow near upper C. Point upper D is on the top inclined slightly to the right of point upper B. A ray from upper B joins upper D with an arrow near upper D. Point upper A is to top right of point upper B. A ray from upper B joins upper A with an arrow near upper A. Angle upper C upper B upper A is labeled as 155 degrees. Angle upper D upper B upper A is labeled as 60 degrees.

The measure of ∠ABD is 60° and the measure of ∠ABC is 155° . What is the measure of ∠DBC ?

Answered by GPT 3.5
To find the measure of ∠DBC, we can subtract the measures of ∠ABD and ∠ABC from 180° because the three angles around point B form a straight line.

180° - 60° - 155° = 215°

Therefore, the measure of ∠DBC is 215°.

To find the measure of ∠JHI, we can subtract the measure of ∠GHJ from the measure of ∠GHI.

∠JHI = ∠GHI - ∠GHJ
∠JHI = 135° - 112°
∠JHI = 23°

Therefore, the measure of ∠JHI is 23°.

To find the measure of ∠DBC, we can subtract the measure of ∠ABD from the measure of ∠ABC.

∠DBC = ∠ABC - ∠ABD
∠DBC = 160° - 92°
∠DBC = 68°

Therefore, the angle measure of DBC is 68°.
