Answer:
D
Step-by-step explanation:
From the triangle inequality, we know that the two small sides must be greater than the largest side. Let's let x be the third side:
However, 15 can also be our largest side. So:
Let's solve for x for both inequalities.
First inequality:
Add:
Flip:
Second inequality:
Subtract 7 from both sides:
So, we have the compound inequality:
Combine:
Our answer is D
And we're done!
3x - 7 = 5x - 13
-3x -3x
5x - 3x = 2x
-7 = 2x - 13
+7 +7
-13+7 = -6
2x = -6
2x/2 = -6/2
x = -3
Answer: x = -3
Answer:
K = -2
Step-by-step explanation:
If y varies directly as x, k (constant) can be found by dividing the y-coordinate by the x-coordinate.
Answer:
8 1/4, 8 4/9, 8 5/8, 8 2/3
Step-by-step explanation:
8 1/4, 8 5/8, 8 2/3, 8 4/9
Answer:
<u>According</u><u> to</u><u> the</u><u> </u><u>given</u><u> </u><u>Attachment</u>
we know sum of all angles in a triangle is 180° .
- Sum of all angles in ∆ = 180°
On substituting the given value we obtain
➥ x + 61° + 70° + 61° = 180°
➥ x + 192° = 180°
➥ x = 180° - 192°
➥ x = -12°
So, the value of x is -12°
