Answer:
x = 7
Step-by-step explanation:
The larger triangle is twice as big as the smaller triangle. Therefore, the length of the side EF is twice as large as the side YZ.
I multiplied 4.5 (the length of YZ) and 2 to get 9. The value of side EF is 3x-12 and should be equivalent to 9.
3x - 12 = 9
I solved this equation by adding 12 to both sides and dividing 3 on both sides.
The value of x is 7.
Answer:
x = 6
Step-by-step explanation:
use alternate angles
Answer:
Set 1 Yes
Set 2 No
Set 3 and Set 4 ???
Step-by-step explanation:
Use the converse of the Pythagorean theorem. Square the lengths and see if 2 results add up to the third result.
So, Set 1
100 + 576 = 676 Therefore we have a right triangle
Set 2
16 + 4 ≠ 36 Therefore we do NOT have a right triangle
I will let you do Set 3 and Set 4. OK?
Answer:
-5 and -3 could both work in this situation
Step-by-step explanation
-5 + 4 = -1
| -1 | = 1
-3 + 4 = 1
| 1 | = 1
