3,10,5 CANNOT be a triangle as 3+5 IS NOT greater than or equal to 10
10,8,5 CAN be a triangle as 8+5 is greater than or equal to 10
a simple way to figure out if three lengths can be a triangle is to take the two smaller numbers and see if they are greater than or equal to the larger number.
Answer:
175.42
Step-by-step explanation:
surface area of square pyramid is given by:
Area= s^2 + 2(s)(l)
where s is the base and l is the slant height
in given problem, slant height l is not given, so by using Pythagoras theorem finding l:
c^2= a^2 + b^2
= 8^2 + 4^2
= 48.49
c = 6.96348
Now putting values of s=8 and l= 6.96 in first formula
Area= 8^2 + 2(8)(6.96)
= 64 + 111.41
= 175.42

Both numbers are the sums because it says that two negative numbers so if we flip that it becomes a whole
Angle 1 = 37 degrees
152 and the angle adjacent to it add up to 180 degrees so
180-152= 28 degrees
All the angles of a triangle add up to 180 degrees so
28 + 115 = 143
180-143 = 37 degrees
169 since it is a square so all sides are equal and 52 divided by 4 is 13 then 13 times 13 is 169.
