Answer:
110 degrees
Step-by-step explanation:
Because these angles are vertical, 5x+15=8x-42. thus, 15=3x-42, 3x=57, and x=19. 5x+15=5(19) +15=110. So, m<CDE=110 degrees.

Answer:
Probability of selected sample is floral = 1 / 3
Step-by-step explanation:
Given:
Number of fabric sample = 6 sample
Number of floral sample from all samples = 2 samples
Find:
Probability of selected sample is floral
Computation:
Probability of a sample = Favorable outcome / Total outcomes
Probability of selected sample is floral = Number of floral sample / Number of fabric sample
Probability of selected sample is floral = 2 / 6
Probability of selected sample is floral = 1 / 3
