Answer:
smallest triangle BCD
x = 15
Step-by-step explanation:
9/x = x/(16 + 9)
x² = 25(9)
x = ±15
For the right triangle to be given in name of three letters such as this, the right angle is most likely to be in the center, in this case letter K. To determine the common trigonometric properties of a certain angle we may use of the mnemonics SOH - CAH - TOA.
sin angle = opposite side / hypotenuse
cosine angle = adjacent side / hypotenuse
tangent angle = opposite side / adjacent side
If we let small letter j, k, and l be the sides opposite to angles J, K, and L, respectively. Then, the cos (L) will be,
cos (L) = j/k
Add the sides then what ever you got add that up with 9 yd
Answer:
23
Step-by-step explanation:
1 + 4 = 5 so we get 1 4 5
then 4+5 = 9, 1 4 5 9
5+9 = 14, 1 4 5 9 14
9+14 = 23, so
1 4 5 9 14 23
23 is the 6th number in this sequence
You would use “square units”
Hope this helps ;)
