The answer should be x=60. ABD are an equilateral triangle all the angles must add up to 180. 60*3=180. Also if you have a protractor you can measure the angle C, the 60 degrees part and measure it against A, D and B. Hope this helps.

HELLP ME PLS QUICK
MAVERICK [17]

Answer:

Both Oscar and Kim will have enough to purchase the book.

Step-by-step explanation:

Oscar takes 30% of the normal price and subtracts it from the normal price. Out of 100% price he takes 30% so the result is: 100-30%= 70% of the normal price. Oscar's first step has the same result as Kim.

Oscar takes 10% of the discounted price (70%) and adds it back. The price will become 70% + 10%*70%= 77% of original price. Kim multiplies the discounted price with 110%, so the price will be: 70% * 110%= 77%. Both also give the same result.

The final price is 77% of the original, it will be: $28.50* 77%= $21.945

Oscar :

28.50 - 0.30(28.50) = 28.50 - 8.55 = 19.95

0.10(19.95) + 19.95 = 2 + 19.95 = 21.95

Kim :

0.7(28.50) = 19.95

1.10(19.95) = 21.95

solve systems of equation. equation number 1: 9 x squared + 4 y squared equals 144. equation 2: x squared plus y squared equals
grigory [225]
9x^{2} + 4y^{2} =144
x^{2} + y^{2}=24

9x^{2} + 4y^{2} =144
 4x^{2} + 4y^{2}=96
by the difference 
5x^{2}=48
so x=\sqrt{\frac{48}{5}} or x=-\sqrt{\frac{48}{5}}
and y^{2}=24-\frac{48}{5}
then y=\sqrt{\frac{72}{5}} or -\sqrt{\frac{48}{5}}
