we know that the sum of all the angles of a triangle is 180
therefore
11x+7x+90=180
18x=90
x=5
exterior angle formed on the ground=180-11x
=180-55
=125
Hope this helps

Answer: 0.09
Step-by-step explanation:
From the question, in a physical education class, there are 21 boys and 9 girls. Each day, the teacher randomly selects a team captain randomly.
The probability that the team captain will be a girl two days in a row assuming no student is absent will be:
Boys = 21
Girls = 9
Total = 21 + 9 = 30
P(pick a girl) = 9/30 = 3/10 = 0.3
P(pick a girl 2 days in a row) = (0.3)²
= 0.09
