Remer<br> 1) 5k? + 10k + 6 = 0
IceJOKER [234]

Ignoring the "?" in your question:

5k+10k+6=0 \iff 15k+6=0 \iff k=-\dfrac{6}{15}

If the "?" is a squared symbol that wasn't caught:

5k^2+10k+6=0

Use the quadratic formula

x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

to get the solutions:

x_{1,2}=\dfrac{-10\pm\sqrt{100-120}}{10}

as you can see, the discriminant is negative, so the equation has no solution.

amm1812

Answer:

see the explanation

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠PQS+m∠SQR=m∠PQR ----> equation A (by Addition Angle Postulate)

we have that

m∠PQR=90° ----> equation B given problem (because is a right angle)

substitute equation B in equation A

m∠PQS+m∠SQR=90°

Remember that

Two angles re complementary is their sum is equal to 90 degrees (Definition of complementary angles)

therefore

m∠PQS and m∠SQR are complementary angles
