Hello!
110% of 90 is: 99.
I hope this was helpful! c:
1. The formula is 180(n-2)/n, where n=sides. so hexagon has 6 sides, so it would be 180(6-2)/6=180(4)/6=720°/6=60° per side.
2. The sum of measures of ANY polygon is ALWAYS 360°
3. Notice that there are 6 sides. This means the total interior angles are 720°. x=127°
4. now, it's talking about a SINGLE exterior angle. So the interior angle is always 360/n, where n=5 here, so 360=5=72°
Answer:
Step-by-step explanation:
<u>Find the area of the rectangle:</u>
- A = (3 + 12)*7 = 15*7 = 105 cm²
<u>Find the area of triangles:</u>
- A = 1/2(3 + 15 - 9)*7 = 1/2*9*7 = 31.5 cm²
<u>Find the shaded area:</u>
- A = 105 - 31.5 = 73.5 cm²
