D is the correct answer:)
Answer:
Angle 1= 58
Angle 2= 64
Angle 3= 58
Step-by-step explanation:
The two smaller triangles are each right triangles and every triangle equals 180 so add 32 degrees and 90 degrees ( 90+32=122) and subtract that from 180 and you get angles 1 and 3 from your isosceles triangle
then you add both angles 1 and 3 from your isosceles triangle which are 58 degrees each (58+58=116) and subtract that from 180 (180-116=64) and you get angle 2
1 ft = 12 inches
23ft you have to multiply 12 by 23 = 276 inches
276 inches = 23 ft
I made a probability tree. Pls. see attachment.
Based on the probability tree I made, below are the probabilities
Probability of a student accepted at both Dartmouth and Harvard is:
50% x 40% = 20%
Probability of a student accepted at Dartmouth but not Harvard is:
50% x 60% = 30%
Probability of a student not accepted at Dartmouth but accepted in Harvard is:
50% x 20% = 10%
Probability of a student not accepted in both schools is:
50% x 80% = 40%
As you can see, these probabilities total 100%
