"When you know one of the roots of a polynomial function, you can use it in order to find the rest of the zeroes of the function, and in music by knowing the root of a chord, a musician can find the remaining notes of the chord."

Given ΔRST congruent to ΔNPQ, m∠R = -7x + 9, m∠N = -10x, find m∠R and m∠N. PLEASE HELP

zepelin [54]

Answer: m∠R=30° m∠N=30°

If ΔRST is congruent to ΔNPQ, then we can infer that m∠R is congruent to m∠N

m∠R=-7x+9

m∠N=-10x

If both angles are congruent, we can solve for x...

-7x+9=-10x
add 7x to both sides
9=-3x
divide both sides by -3
-3=x

Now that we know the value of x, we can solve for the measure of the angles.

m∠R=-7x+9
m∠R=-7(-3)+9
m∠R=21+9
m∠R=30°

m∠N=-10x
m∠N=-10(-3)
m∠N=30°
