What do you need to find I need to know that so I can solve it
Answer:
17 cm
Step-by-step explanation:
To find the perimeter of any figure, you must add all the side lengths. In a triangle, there are three side lengths to add, and in this case, they are 3 cm, 6 cm, and 8 cm long. So:
3 + 6 + 8 = 17 cm
∴, the triangle's perimeter is 17 cm.
Answer:
2
−
9
x
Step-by-step explanation:
Using the principle of parallel lines, the value of x in the given triangle is calculated to be 8
<u>The</u><u> </u><u>smaller</u><u> </u><u>triangle</u><u> </u><u>can be</u><u> </u><u>expressed</u><u> </u><u>as</u><u> </u><u>:</u>
- Side / base = 6/x ----(1)
<u>The</u><u> </u><u>larger</u><u> </u><u>triangle</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>expressed</u><u> </u><u>as</u><u> </u><u>:</u>
- Side / base
- Side = 6+9 = 15
- 15/20 - - - - - (2)
<u>Equating</u><u> </u><u>(</u><u>1</u><u>)</u><u> </u><u>and</u><u> </u><u>(</u><u>2</u><u>)</u><u> </u><u>:</u>
6/x = 15 / 20
15x = 20 × 6
15x = 120
x = 120 / 15
x = 8
Therefore, the value of x in the triangle is 8.
