Answer:
The number of women teachers attending the lecture is 1.
Step-by-step explanation:
Denote the variables as follows:
<em>M</em> = men
<em>W</em> = women
<em>T</em> = teacher
The data provided is:
n (M) = 23
n (W) = 29
n (T) = 4
n (M ∪ T) = 24
Compute the number of men teachers as follows:


Compute the number of women teachers as follows:



Thus, the number of women teachers attending the lecture is 1.
Answer:
15° , 45°, 120°
Step-by-step explanation:
sum the parts of the ratio, 1 + 3 + 8 = 12 parts
the sum of the 3 angles in a triangle = 180° , then
180° ÷ 12 = 15° ← value of 1 part of the ratio, then
3 parts = 3 × 15° = 45°
8 parts = 8 × 15° = 120°
the 3 angles are 15° , 45° , 120°
38.4 is the answer super easy and could just look it up
