Answer 13

for 1st one->
Rule->the sum of adjacent angles in a parallelogram is 180
explanation->
<DCB +<ADC=180
60+<ADC=180
<ADC=120


for 2nd one->
Definition of perimeter->perimeter is the sum of all side lengths
Explanation->
perimeter=\(60+2 \times (10)+ 5 \times (20)\)
\(perimeter=60+20+100\)
\(perimeter=180inches\)

for 3rd one->
Formulas->
formula for \(Circumference\) of a circle with radius \(r\) =\(2 \pi r\)
formula for \(Area\) of a circle with radius \(r\)=\(\pi r^2\)
Explanation->
\(Circumference=2 \pi r = 2 \pi 10 =20 \pi \)
\(Area= \pi r^2=\pi 10^2=100 \pi\)

for 4th one->
Formula->
\(Distance~between~ 2~ points= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)
Explanation->
coordinates of home \((x_1,y_1)\) =\((-6,-3)\)
coordinates of office \((x_2, y_2)\)=\((-4,4)\)
distance will be->\(\sqrt{-6-(-4))^2+(-3-(4))^2}\)
distance=\(\sqrt{(-2)^2+(-7)^2}\)
distance=\(\sqrt{53}\)
distance~7.4km
