∠3 and ∠4 are supplementary angles. m∠4=49°
What is the measure of ∠3?

Options:

131

41

139

49

A. 131

Step-by-step explanation:

if two angles are supplementary, that means the total measure of both angles is 180 degrees. 180-49=131

The answer would be the first one 131

Step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.
