ES is half of EF since a chord is bisected by the radius. ES = 10
Answer:
C
180(.6) because 40% off is 0.4 and what is left over is 60% or 0.6. When you multiply this you get 108. 5% sales tax is a 5% increase, so multiple 108(1.05) and you get $113.40.
Answer:
Pythagorean's theorem: a²+ b²= c²
Sines: sin A = a/c, sin B = b/c.
Cosines: cos A = b/c, cos B = a/c.
Tangents: tan A = a/b, tan B = b/a.
Step-by-step explanation:
For example, if the side a = 22 and the angle A = 41°, we can use a sine and a tangent to find the hypotenuse and the other side. Since sin A = a/c, therefore c = a/sin A = 22/sin 41. Using a calculator, this is 22/0.6561 = 33.5314. Also, tan A = a/b, so b = a/tan A = 22/tan 41 = 22/0.8693 = 25.307.
Answer:
d
Step-by-step explanation:
3(x - 9)
3×x - 3×9
3(x) - 3(9)
The pen is 
centimeters long when scale is 
inches long and pen is 
shorter then the scale.
How to find the how much long is the pen ?
Scale is 
long and
We know that
And pen is shorten then the scale
So the length of the pen is
