In this parallelogram, the measure of angle b exceeds the measure of angle a by 30 What is the measure of angle c

Answers

Answer 1

Answer: angle a +angle b = 180 degrees
angle a + angle a + 30 = 180
2*angle a = 150
angle a = 75degrees
angle b = 75+30 = 105 degrees
now, angle b +angle c = 180
so, angle c = 180-105 = 75 degrees

Answers

Answer:

s=5/14

Step-by-step explanation:

cancel equal terms on both sides of the equation

0=-2 x |14s-5|

swap the sides of the equation

-2 x |14s-5|=0

divide both sides of the equation by -2

|14s-5|=0

when the absolute value of 14s-5= 0, then 14s-5=0

move the constant to the right-hand side and change its sign

14s=5

now divide both sides of the equation by 14

s=5/14

how much did briana save by purchasing a backpack that cost $45 with a sales promotion of 20% off instead of a backpack that cost $42 with a sales promotion of 10% off?

Answers

Start by doing a proportion for each one. 20/100= x/45. 45 times 20 equals 900. 900 divided by 100 equals 9. So 20% off is $9 which makes you pay $36. Do the next proportion. 10/100=x/42. 42 times 10 is 420. 420 divided by 100 equals 4.2. You would get off $4.2 which makes you pay $37.8. $37.8-$36= $1.8. Your answer is $1.8
