Answer:
Left angle = 60°
Top angle = 120°
Right angle = 60°
Step-by-step explanation:
Use what you know about angle relationships to set up equations you can solve for each variable.
The top top angle, for example, added to one of the other angles must equal 180° because they are supplementary.
You have two variables, so you need at least two equations (I made three but only used two).
The work is in my attachment, comment of you have questions.
15 + x = -7
First, subtract 15 from both sides. / Your problem should look like:
Second, subtract -7 - 15 to get -22. / Your problem should look like:
Answer: x = -22 (D)
First, subtract 15 from both sides. / Your problem should look like:
