Using supplementary angles, it is found that the measures of the angles are given as follows:
<h3>What are supplementary angles?</h3>
Supplementary angles are two angles whose sum is of 180º.
An interior angle is supplementary with it's exterior angle, hence:
m<a + 150º = 180º -> m<a = 30º.
The sum of the three interior angles of a triangle is of 180º, hence:
30º + m<b + 60º = 180º
90º + m<b = 180º
m<b = 90º.

#SPJ1
Answer: 5/8 or 0.625
Step-by-step explanation:
3/2x1/4= 3/8
Then, 3/8x5/3= 15/24
15/24 simplified equals 5/8. 5/8 in decimal form is 0.625
Answer:
6x^2 - 2
Step-by-step explanation:
plug in f(x) into the g(x) formula given
g(f(x)) = (3x)^2 + 1
simplify
= 9x^2+2
plug in g(x) into the f(x) formula given
f(g(x)) = 3(x^2+1)
distribute
= 3x^2 +3
set g(f(x)) - f(g(x))
(9x^2+2) - (3x^2+3)
carry the negative
9x^2+2-3x^2-3
simplify by combining like terms
6x^2-2
Answer:
Step-by-step explanation:
80% mean 80/100=8/10=4/5
4/5 of 40=4/5 times 40/1=160/5=32
answer is 32 quetsions
easier way
10% times 8=80%
10% of 40=4
4 times 8=32
