The answer is 7.9 × 10⁻⁴
0.00079 = 7.9 × 0.0001
The number of decimals is a negative value of the exponent. For example:
0.1 = 10⁻¹
0.01 = 10⁻²
0.001 = 10⁻³
0.0001 = 10⁻⁴
0.00079 = 7.9 × 0.0001 = 7.9 × 10⁻⁴

Step-by-step explanation:
Answer:
no
Step-by-step explanation:
Similar triangles have angles with the same measures.
angles in the first triangle are 50°, 60°, 70°.
angles in the second triangle are 50°, 50°, 80°.
The angles do not have the same values, so the triangles cannot be similar.

<em>Comment on the question</em>
When 2 of the three angles are different, the third angle cannot make the triangles similar. We don't even need to compute the third angle to answer this question.
Answer:
∠C = 37° ,
AB = 26.54 cm ,
BC= 33.27 cm
Step-by-step explanation:
Given that in triangle ABC
∠A = 39° AC = 20 cm
∠B = 104°
∵ sum of all the three angles of triangle = 180°
So, ∠C = 180° - ( ∠A + ∠B)
∠C = 180° - (39° + 104°)
∠C = 37°
Now Tan 37° = ![\frac{AC}{AB}](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7BAB%7D)
Or, AB = ![\frac{20}{tan 37°}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7Btan%2037%C2%B0%7D)
So, AB = 26.54 cm
Again, Sin 37° = ![\frac{AC}{BC}](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7BBC%7D)
So, BC = ![\frac{20}{sin 37°}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7Bsin%2037%C2%B0%7D)
Or, BC = ![\frac{20}{0.601}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B0.601%7D)
∴ BC= 33.27 cm
Hence ∠C = 37° , AB = 26.54 cm , BC= 33.27 cm Answer
So basically you have to multiply 100 by every single number after it like 100*99*98*97*96......
Hope this helps!
