Me db is a diagonal of parallelogram abcd, what is the measure of adb

The sum of the measures of the interior angles of a polygon of n sides is

180(n - 2)

A parallelogram has 4 sides, so n = 4.

The sum of the measures of the interior angles of a parallelogram (and all quadrilaterals) is

180(4 - 2) = 180 * 2 = 360

Also, opposite angles of a parallelogram are congruent.

Angles A and C are congruent, so m<A = m<C = 112

m<ADC = m<ABC since they are opposite angles.

m<ADC + m<ABC + m<A + m<C = 360

m<ADC + m<ADC + 112 + 112 = 360

2m<ADC = 136

m<ADC = 68

m<ADB + m<BDC = 68

m<ADB + 27 = 68

m<ADB = 41

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
