First calculate the remaining angle in the triangle. which is going to be 180-65-75 = 40.
and basically the remaining angle should be the same as x. because of the (vertical opposite angle) theory.
therefore, x should be 40°
Answer: 1102
Explain: 8 x 9 = 72
72 x 3 = 216
216 x 5 = 1080
1080 - 4 = 1076
1076 + 28 = 1104
1104 - 2 = 1102
Answer:
$70.47
Step-by-step explanation:
Since the cost of the aquarium with the 15% discount is $59.90 then $59.90 is 85% of the original price. Remember 100-15=785. To find the original price set up a proportion with these values:
![\frac{59.90}{x}=\frac{85}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B59.90%7D%7Bx%7D%3D%5Cfrac%7B85%7D%7B100%7D)
Solve for the original price by cross multiplying numerator with denominator.
x(85) = 59.90(100)
85x = 5990
x= $70.47
X will equal 4 because 4^2=4*4 which equals 16
