Perimeter is amount out all sides added together.
<span><u><em>Answer:</em></u>
83.21 mm.<span>
<u><em>Explanation:</em></u>
<u>Circumference of a circle is is found by using the formula:</u>
C=πd.
C is the Circumference.
d is diameter.
π is the ratio for Pi,
<u>In this case we will use:</u>
3.14 instead of π
d = 26.5 mm
<u>Plug in the known values. </u>
C=(3.14)(26.5) = 83.21 mm</span></span>
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°
