Answer:
Well you can either straight up subtract from the total degrees of a triangle using the sum of both of the given angles, which would equal x, or you can make an equation. I’ll do both.
180-78-51=51, x=51
78+51+x=180
129+x=180
x=180-129
x=51
Step-by-step explanation:
price difference= $45-$36
=$9
now,
x% of $45=$9
or, x/100 ×45 =9
or, x/20 ×9=9
or, x/20=1
therefore, x= 20%

Answer:
LM = 6 cm
Step-by-step explanation:
A square has all the sides equal in length. The opposite sides of a square is parallel to each other and all the angles are equal to 90°.
Therefore , the square QRST has all it sides equal in length. Likewise the square KLMN .
The ratio of side QR to the length side KL is 3:2 . If the side ST = 9 cm , The length of side LM can be gotten below.
ST = 9 cm since QRST is a square all the other sides are 9 cm . The length of KLMN is equal for all sides too. The ratio for any sides of square QRST to any sides of square KLMN is the same through out.
Therefore,
3/2 = 9/LM
cross multiply
3LM = 18
divide both sides by 3
LM = 18/3
LM = 6 cm
