Answer:
Step-by-step explanation:
The first rule is that 2 of the sides must be bigger than the third.
4 and 7 makes 11 which is not bigger than 12, so A is not an answer.
5 + 7 = 12 That does not exceed 12, so the second one is not an answer
12 12 and 7 works perfectly. It makes an isosceles triangle. Any two of the three sides added together is larger than the third side.
If you put 19 20 or 21 into what you think might make a triangle, you would be incorrect. 12 and 7 makes 19. 19 is too large because 12 and 7 will lie flat on 19. No triangle works.
So only 12 works.
In short, 5<x<19 will create a triangle. Anything outside that inequality will not.
Answer:
Step-by-step explanation:
let the length of shortest side be x
and length of second side be 2x
and third side be x+17
given , perimeter = 173 feet
therefore , x+2x+x+17 =173
4x =173-17
4x =156
x = 156/4
x = 39
therefore ,
length of :
shortest side = 39 feet
second side =78 feet
third side =56 feet

Answer: slope = 10/15
Step-by-step explanation: Identify two points in the graph
Make one of them (x1, y1) and the other (x2, y2)
Then use the slope equation:m= y2- y1/ x2 - x1
Answer: 8 , 60 , 23.3
Step-by-step explanation: 2/3 x 12 = 8
3 of 20 = 60
10/9 x 21 = 70/3 = 23.3
<span>Given
∠FHJ = 60°
</span><span>∠FGH = 28°
</span>∠FHG = 180 - ∠FHJ
∠FHG = 180 - 60
∠FHG = 120
∠HFG = 180 - (28 + 120)
∠HFG = 180 - 148
∠HFG = 32
