The measure of two adjacent angles of parallelogram are in the ratio 3: 7 find the measure of each angle of parallelogram

from the pararellelogram has 4 angles is 180° and each 2 angles of this is equal so the ratio is 3:7 it will be 3x and 7x.

from each 2 angles is equal it will be 3x+7x =180/2 so 10x=90 ; x=9

Substitute x=9 in 3x and 7x ; the angles is 27 and 63

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
