A and a' are vertical angles, therefore a' = a
We know: The sum of the measures of triangle is always 180°.
Therefore: a' + b + d = 180° → d = 180° - a - b.
d and c are adjacent angles, therefore d + c = 180°
substitute
180° - a - b+ c = 180° |-180°
-a - b + c = 0 |+a |+b
c = a + b
Answer:
Step-by-step explanation:
pythagoras theorem
a^2+b^2=c^2
8^2+9^2=x^2
64+81=x^2
145=x^2
=x
Hi!
Given the ratio of boys to girls, which is 6/9, we can find the number of boys in a total of 75 students like this:
(6/9) * 75 = (6*75)/9 = 450/9 = 50
There are 50 boys.
Hope this helps!
