Answer:
or
Step-by-step explanation:
Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.
Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.
Answer:
2.5 miles
Step-by-step explanation:
Y = -3x - 40. Use the distributive property to get the slope and move the 10 to the other side to isolate the y
Sec^2x+csc^2x=sec^2xcsc^2x
Divide both sides by csc^2x
sec^2x+(csc^2x/csc^2x)=sec^2xcsc^2x/csc^2x
sec^2x=sec^2x
Divide both sides by sec^2x
0=0 which is a true statement.
Hope this helps :)
Answer C
| (5)(2)+(0)(2) = 10, (5)(-1)+(0)(-2) = -5 |
