Answer:
a. 38.5
Step-by-step explanation:
The triangles are similar. That means that the ratios are the same.
x/14 = 11/4
x/31.5 = 11/9
Let's use the top one
x/14 = 11/4
4x/14 = 11
4x = 154
x = 38.5
We know that angle2+angle3+90=180 (since we see the right angle in the corner and all internal angles add up to 180) so
angle3=40
subsitute
angle2+40+90=180
angle2+130=180
subtract 130
angle2=50
answer is 50 degrees

Answer:
24750
Step-by-step explanation:
Given that 6 freshmen, 5 sophomores, 6 juniors, and 5 seniors are eligible to be on a committee
16 students be chosen if it is to consist of exactly 4 juniors and exactly 3 seniors, and the rest must be freshmen or sophomores
i.e. dance committee will have 16 students out of which
4 juniors 3 seniors 8 freshmen or sophomores from
6 juniors, 5 seniors and 5 sophomores and 6 freshmen
Junior can be selected in 6C4 = 15 ways
Seniors in 5C3 = 10 ways
Freshman or sophomores in 11C8 = 165
The total no of ways = product of these three
=
