Answer:

Step-by-step explanation:

The answer is A. more than one, because you can create one, but then you can move the angles around. So if the angles in order go 10°, 80°, 90°, you could change the order to 90°, 10°, 80°, or something. I hope this helps!

Its correct I just finish my test with 100%

30 70 80 how many triangles cant you construct with these measurments

Alinara [238K]

Answer:

One triangle can be constructed.

Step-by-step explanation:

Recap that all the interior angles in a triangle add up to 180. With the given measurements of the angles, 70 plus 80 plus 30 equals 180. Each triangle has the sum of 180 degrees. Therefore, there can only be one triangle that can be constructed. I think you were suppose to put can, not can't. Hope this helps!

1) Shannon and Kristoph are dividing numbers written in scientific notation.

mihalych1998 [28]

Answer:

The answers will have the same value, beacuse both scientific notations have the same coefficient, 4.2 and 1.4. Also, if you mentally subtract the exponents of those powers, you would have the same exponent. So, equal coefficient and equal exponent will give the same result.

The value of each expression can be found by dividing coefficients and powers.

$\frac{4.2 \times 10^{9} }{1.4 \times 10^{4} }=3 \times 10^{9-4} = 3 \times 10^{5}$

The value of each expression in standard form is

$3 \times 10^{5}=300,000$

Remember that standard form refers to the number without the ten-power.
