Answer:
60° = <em>m</em>∠<em>CED</em>
30° = <em>m</em>∠<em>AEB</em>
Step-by-step explanation:
Since 90° is the <em>m</em>∠<em>CEB</em><em>,</em><em> </em>we already know the angle measures of the other two that got to be half and half of each other:
m∠<em>AEB</em> = ½<em>m</em><em>∠</em><em>CED</em>
This is like the 30°-60°-90° theorem. Always keep these in mind because you will never know when they will come in handy. The other one is called the 45°-45°-90° theorem, which in this case would not apply because two legs would have to congruent, which in this case they are not.
I am joyous to assist you anytime.
You haven't provided the required roots, but I can tell you how to do this kind of exercises in general.
If the coefficient is 1, i.e. the equation is written like
, then you can say the following about the coefficients b and c:
is the opposite of the sum of the roots
is the multiplication of the roots.
So, for example, if we want an equation whose roots are 4 and -2, we have:
So, the equation is
If your roots are rational, you can work like this: suppose you want an equation with roots 3/4 and 1/2. You have:
And so the equation is
In order to have integer coefficients, you can multiply both sides of the equation by 8:
