What is the value of x in the figure

100 °

Step-by-step explanation:

corner anglesA = C = 80 °

corner anglesB = D = 100 °

side a lengtha = 5.5 in

side b lengthb = 3.4 in

diagonal lengthp = 5.9404956471339 in

diagonal lengthq = 6.9520149213292 in

heighth = 5.4157652457182 in

perimeterP = 17.8 in

areaK = 18.413601835442 in²

Formula:

A = C

B = D

A + B = 180° = π radians

for a parallelogram that is not a rectangle or square,

0 < A< 90° (0 < A < π/2),

90° < B < 180° (π/2 < B < π)

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
