Angles 1 and 2 are complementary and congruent. what is the measure of angle 1? 30° 45° 50° 75°
lesantik [10]

see the attached figure to better understand the problem

we know that

1) If angle 1 and angle 2 are complementary angles

then

m∠1+m∠2=90\° ------> equation A

2) If angle 1 and angle 2 are congruent angles

then

m∠1=m∠2 ------> equation B

Substitute equation B in equation A

m∠1+(m∠1)=90\°

2m∠1=90\°

m∠1=45\°

therefore

<u>the answer is</u>

45\°

Solve this quadratic equation by completing the square.
nadya68 [22]

Answer:

x=-3+\sqrt{27}\\  x=-3-\sqrt{27}

Step-by-step explanation:

Let's find our C value for the quadratic equation.

(\frac{6}{2})^{2} = 9

That is our C. Since we added 9 to one side, we have to do the same to the other. We get:

x^{2} +6x + 9 = 18 + 9\\x^{2} +6x + 9 = 27

Now, lets form the left side as a binomial squared.

(x+3)^{2} = 27

Let's square both sides now:

x+3 = (+/-)\sqrt{27}

Now, we subtract 3 from both sides to isolate the variable, X:

x= -3(+/-)\sqrt{27}

This means that the answers are:

x=-3+\sqrt{27}\\  x=-3-\sqrt{27}

I do not understand your answers though. Answer A makes no sense, answer B is 221, answer C is 115, and answer D also does not make sense. If you could clarify this portion, maybe I can help you find your alphabetic answer
