Answer:
NO because 7+5=12
The sum must be larger (not equal to) the longest side. If it's exactly the same, there's no room to for the shorter two sides to angle up to form a triangle.
Answer:
The perimeter is 112 m
Step-by-step explanation:
The perimeter is the sum of all the edges
26+ 12 + 18 +? + ?+ 30
The two question marks add to 26 so replace them with 26
26+ 12 + 18 +26+ 30
112
The perimeter is 112 m
Answer:
-4 and -1
Step-by-step explanation:
If a number is in a absolute value sign it can never be negative.
Answer:
x = 31 and x = 15
Step-by-step explanation:
(a)
(3x + 31) and (2x - 6) are a linear pair and sum to 180° , then
3x + 31 + 2x - 6 = 180
5x + 25 = 180 ( subtract 25 from both sides )
5x = 155 ( divide both sides by 5 )
x = 31
(b)
3x and (4x - 15) form a right angle and sum to 90° , then
3x + 4x - 15 = 90
7x - 15 = 90 ( add 15 to both sides )
7x = 105 ( divide both sides by 7 )
x = 15
Answer:
They are proportional.
Step-by-step explanation:
400/12 = 33 1/3
300/9= 33 1/3
