Answer:
A pythagorean identity means that for any angle
,
.
This also means
The symbol, theta (
) represents one of the acute angles in the right triangle. The hypotenuse (familiarly c in the regular pythagorean theorem) is 1. The triangle base is
, and the height (side perpendicular to the base, making a right angle) is
. The angle theta is opposite the
side.
Step-by-step explanation:
The pythagorean theorem applies to right triangles, which always have a 90 degree angle. Pythagorean identities are used to simplify trigonometric expressions/evaluate trig functions and to find the trig ratios in a right triangle.
Answer:
No, Owen wants to spend 105/100 of his money.
Step-by-step explanation:
HE wants to spend 2/10, 3/10, and 55/100 or 5.5/10, but if we add up all of the numbers we would get 10.5/10 meaning he would he 5 dollars short.
(2x - y = -2)2
5x - 2y = -7
4x - 2y = -4
Subtract both
x = -3
5(-3) - 2y = -7
-15 - 2y = -7
-2y = 8, y = -4
Solution: (-3,-4)
Answer:
A graph that is good for paired data called a scatterplot. The graph has one coordinate axis and symbolises the paired data.
Step-by-step explanation:
4cm, as if two of the sides add up to be the same length as the first side then the triangle would be a straight line.
