Round 813 to the nearest ten
Look at the number next to the tens place. It is a 3. Because 3 is less than 5, round down.
813 rounded to the nearest ten is 810
hope this helps
Are three or more points which lie in the same plane. Recall that a plane is a flat surface which extends without end in all directions. It's usually shown in math textbooks as a 4-sided figure. You can see that points A, B, C and D are all coplanar points on a single plane:

Answer:
Step-by-step explanation:
Use a^2 + b^2 = c^2 to get the third side.
a = 12
b = ?
c = 37
a^2 + b^2 = c^2
144 + b^2 = 37^2
144 + b^2 = 1369 Subtract 144 from both sides.
<u>-144 -144</u>
b^2 = 1225 Take the square root of both sides
sqrt(b^2) = sqrt(1225)
b = 35
Perimeter = a + b + c
Perimeter = 12 + 35 + 37
Perimeter = 84
