Answer:
x≈20.23
Step-by-step explanation:
![sin\alpha = \frac{opposite}{hypotenuse} \\sin(40) = \frac{13}{x}\\x=\frac{13}{sin(40)} \\](https://tex.z-dn.net/?f=sin%5Calpha%20%3D%20%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D%20%5C%5Csin%2840%29%20%3D%20%5Cfrac%7B13%7D%7Bx%7D%5C%5Cx%3D%5Cfrac%7B13%7D%7Bsin%2840%29%7D%20%5C%5C)
x≈20.23

Answer:
9 × 2^(13)
Step-by-step explanation:
hello :
the nth term is : An =A1 × r^(n-1)
a common ratio is : r and A1 the first term
in this exercice : r= -3-(-7)36/18 = 18/9 =2 A1 = 9
when : n =14 you have the 14rd term A14
A14 = 9 × 2^(14-1) = 9 × 2^(13)
Answer:
Step-by-step explanation:
we can have infinite similar triangles with different side lengths but if the base length is same then two triangles on the opposite side of base.
On one side of base only one triangle can be formed.
