The percentage of yellow tint in the new mixture will be 39.1304...%
<em><u>Explanation</u></em>
A mixture of 60 liters of paint is 25% red tint, 30% yellow tint and 45% water.
So, the amount of yellow tint liters.
Now, 9 liters of yellow tint are added to the original mixture. So, the <u>total amount of yellow tint in the new mixture</u> will be: liters.
And the <u>total amount of the new mixture</u> will be: liters.
So, the percentage of yellow tint in the new mixture
A heptagon has seven sides. The measure of the final interior angle of the heptagon is 124°.
<h3>What is heptagon?</h3>A heptagon, sometimes known as a septagon, is a seven-sided polygon. The heptagon is also known as the septagon, which combines the prefix "sept-" with the Greek suffix "-agon," which means "angle."
A heptagon has 7 sides therefore, the sum of the interior angle of the heptagon can be written as,
As it is said in the problem that the sum of the all the angles of the heptagon except one is 776°, therefore, the measure of the last angle of the heptagon is,
The measure of the last angle = 900° - 776° = 124°
Hence, the measure of the final interior angle of the heptagon is 124°.

Answer:
54°
Step-by-step explanation:
Since the radius is not given, i'm going to assume that you are being asked for the measure of Arc FE, which is the angle the arc makes on the circumference when measured from the center of the circle.
Please refer to attached.
We can observe that FG and GE are both radii of the circle, hence they will have the same length. This also means that triangle FGE is an isosceles triangle. Which in turn means that ∠GFE = ∠GEF = 63°.
With this we can find the measure of arc FE
= ∠FGE
= 180° - 63° - 63°
= 54°
Hope this helps!
