36 is what I got for this question
Answer:
Step-by-step explanation:
a
sum of angles of a quadrilateral=360°
4x+5x+20+5x-10+3x+10=360
17x=360-20
17x=340
x=340/17
x=20
b.
sum of angles= (n-2)×180
where n is the number of sides.
5x+4x+2+5x+6+2x-2+3x+5+x-10=(6-2)×180
20x+1=720
20x=719
x=35.95
When rates are expressed as a quantity of 1, such as 2 feet per second<span> or </span>5 miles per hour<span>, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.</span>
