Hey there!
42%= 42/100
<span><span>42/100</span>=<span>2/2</span>×<span><span>21/50</span></span></span>
<span><span><span>
</span></span></span>
<span><span><span>So 21/50 is the simplest form of 42%
</span></span></span>
<span>6x^2 + 11x - 10 is the answer
hope it helps</span>
The answer should be A because a rational # is a # that can be put in a fraction.
The angle x and 70 are alternate interior so that means they measure the same.
In an isoceles triangle the base angles are the same so that means that both the x angles are 70.
Now we can subtract their sum by 180 to find the measure of angle 1.
180 - (70 + 70) = 40
So the measure of angle 1 is 40.
Hope this helps :)<span />
