Answer:
125,000
Step-by-step explanation:
Take the Japanese yen and divide by 12
1,500,000 divided by 12 = 125,000
Answer:y=-1/5-x
Step-by-step explanation:
Answer:
The answer to this inequality would be x>2
Answer:
x = 8*root3
y = 16
Step-by-step explanation:
You can use tangent and cosine of 60° to find x and y, BUT THERE'S A SHORTCUT. You pointed out that its a 30°-60°-90° triangle. That is a special right triangle. Here's the shortcut:
the longest side (hypotenuse) is double the shortest side. We have an 8 on the shortest side, so the hypotenuse (longest side) is 16. This ALWAYS works for 30°-60°-90° triangles!
Another shortcut:
The longer leg is the shorter leg × root3.
This ALWAYS works on 30°-60°-90° triangles.
So on your triangle, the short side is 8, that means the longer leg is 8×root3.
ta-daaaa!
X^2 -61 =20
X^2= 81x =9 x=-9
