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!
Answer:
∠7 = 34°
Step-by-step explanation:
Since a and b are parallel lines then
∠3 and ∠7 are corresponding angles and congruent, so
∠7 = ∠3 = 34°
C - 9.5 ≤ 9.5
+ 9.5 ≤ + 9.5
C ≤ 19.0
