Answer:
substitution is distributive for letters
ie) when we work out for 2x + 5 and 3x -4
we can set = to each other distribute to find x then plug in.
plug in means substitute.
Step-by-step explanation:
transitive is distributive for values for same coefficients in problem solving like Pythagoras a + b = c. but that is not equation checking unless equation replaces it. Answer is substitution for distributive letters.
Answer:
False
Step-by-step explanation:
The short reason the statement is false is, "it depends on what you mean by <em>direction angle</em>".
The long reason the statement is false is that "direction angle" sometimes refers to a navigation direction that is specified in terms of compass directions. For example, you might have N20°E, or S80°E. The angle measure in such directions is 0 to 90°. It does not take on a negative value when the direction is expressed in the standard form, an angle east or west from north or south.
An arbitrary vector is an expression that has a magnitude and direction. Such a quantity can have either or both values be positive or negative and of <em>any magnitude</em>. There is no reason for direction to be restricted to values in the range ±90°.

Step-by-step explanation:
Answer:
<em>L = 131 feet</em>
Step-by-step explanation:
<u>Right Triangles</u>
The cable, the ground, and the radio tower form a right triangle with an angle of 90° located where the ground and the tower meet.
The cable is the hypotenuse of the triangle and the angle of 50° is opposite to the height of the radio tower.
To find the hypotenuse L we use the sine ratio:
Solving for L:
Calculating;
L = 131 feet
