Answer:
First one: Rotation
Second one: Translation
Third one: Reflection
Fourth one: Translation
Step-by-step explanation:
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:
8 < 2
Step-by-step explanation:
8x + 5 > 15
8x > 15 - 5
8x > 10
x < 2

72 = 6*12 = 3*2 * 4*3 = 3*2*2*2*3
72 = 2*2*2*3*3
72=2^3 * 3^2
