If you add up the two smaller sides, you should get a number greater than the longest side. Then you know it is a triangle.
For example: 3, 4, 5.
3 + 4 = 12.
12 > 5; so three, four and five make up a right triangle.
2, 3, 5
2 + 3 = 5
5 is not greater than five, so that would be not be a triangle.
Answer:
A 9 12 and 13
Step-by-step explanation:
Answer:
It is 90 degrees
Step-by-step explanation:
Answer: y=2x+14
Explanation:
Y=mx+b
Y= 2x-4
M=2
Y= 2x+b
2 = (2 x -6) + b
2=-12+b
12+2=12+b
-12
14=0+b
14=b
Y=2x+14
The angle to the left of angle 1 is 70, so angle 1 is equal to 180 - 70 - 70 which is 40,
