Answer:
<h2>137°</h2>
Step-by-step explanation:
The pentagon RSTYZ is a regular polygon. Therefore all angles are congruent.
If m∠RST = 108°, then m∠STY = 108°.
We have the equation:
m∠UTY + m∠STY + m∠STU = 360°.
Substitute m∠STY = 108° and m∠UTY = 115°.
115° + 108° + m∠STU = 360°
223° + m∠STU = 360° <em>subtract 223° from both sides</em>
m∠STU = 137°
So first let’s simplify each term by adding the numbers together. Now we have 10/5 + 9/3. We are still working with each term individually, so next let’s simplify by dividing. 10/5 is 5, and 9/3 is 3, so now we have 5+3 which equals 8. Hope this helps!
Note that there are some useless information here. But all you need to know is that the area of a trapezium is the average of the 2 parallel bases multiplied by the height.
Area = (32 + 24) / 2 * 9 = 252
Since 5 cans of stain can only cover an area of 250, you will need 6 cans of stain.
