Rly rly need help on this

D    73º

Step-by-step explanation:

Total angles

a = (sides - 2) * 180

a = (5 - 2) * 180

a = 540

Missing angle

x = 540 - (104 + 118 + 96 + 115)

x = 107

a is supplementary to x

m∠A = 180 - 107

m∠A = 73º

Step-by-step explanation:

funny i had the exact same queston like this anyways

pentagon=5 sides

5-2=3

3*180

540

add all them together

104+118+96+115=433

540-433

107

since a line equals 180

180-107=

73

I think you may have the same worksheet as me so here

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
