Answer:
60 degrees
Step-by-step explanation:
BWA is an isosceles triangle, meaning that BW and WA are equal in length.
Thus, we have that ABW and WAB are congruent to each other.
ABC is a complementary angle, so ABW and CBD add up to 90 degrees.
ABW is 30 degrees, so we have 30 degrees+ CBD=90 degrees.
Subtracting thirty degrees from both sides we get CBD=60 degrees.
Hope this helps!
- Complementary angles add to 90 degrees.
- Supplementary angles add to 180 degrees.
- Vertical angles are equal.
So, the answers are (in degrees):
6) 47, 137, 43
7) 49, 131, 49
8) 18, 72, 18
9) 13, 77, 167
14 because Mark has none, Cat has 8 and Sophia has 6 so 8+6=14.
