10 ^-4
Use the negative exponent rule to get:
1/10^4 = 1/10,000 (fraction answer) or 0.0001 (decimal answer)
Answer:
the lines are parallel
Step-by-step explanation:
you can tell they are parallel by graphing them
Did you mean "small" or did you mean "shortest?"
Let's assume that the shortest side has length 3. This would be opposite the 30 degree angle. We can form and solve an equation of ratios to solve this problem. Since this is a 30-60-90 degree triangle, the perimeter could be 1x + sqrt(3)x + 2x. 1x is the shortest side, so 1x = 3, and x=3.
Then the perimeter, 1x + sqrt(3)x + 2x, would be 3 + 3sqrt(3) + 6,
or
3(sqrt(3)+2).
<h2>
Answer: 1st one</h2>
two-base angle are equal
let take a base angle as x
<h3>2x + 98 = 180</h3><h3>2x = 180 - 98</h3><h3>x = 2/2</h3><h3>x = 1</h3>
X - 2y = -3....multiply by 2
-2x + 4y = 6
----------------
2x - 2y = -6 (result of multiplying by 2)
-2x + 4y = 6
----------------add
0 = 0
This system of equations has infinite solutions
