Answer:
16 minutes
Step-by-step explanation:
80% of 20 is
80/100 * 20 = 16
Answer:
Step-by-step explanation:
If it’s proportional, then when X is 1, y is 2.6, you get that by dividing 275.5 by 29
so when y is 408.5, x is 156.91
I believe that is correct.
Answer:
12
Step-by-step explanation:
diameter is 2r
r=6
6*2=12
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.
