Answer:
Step-by-step explanation:
to find slope: the formula is:
(y2-y1) / (x2-x1)
in this case it is:
(-9-(-2)) / (-10-(-2))
-7/-8
and thats the slope (that was for question one, and also an example, now do the same for questions 2, 3 and 4!!
hope thsi helps!!
Answer:
Step-by-step explanation:
we know that 100 cm are equal to 1 meter
there are 4 "groups" of 25 cm in one meter
the worm needs 76 seconds to travel a meter, in case you need to know that
Answer
The equation simplified is: r=x+1
The quastion is asking us to determine the measure of angle M in a right triangle LMN. We know that angle N is a right angle and that LM = 76 ( Hypotenuse ) and MN = 40 ( Adjacent ). We will use trigonometry: cos M = Adjacent / Hypotenuse = 40 / 76 = 0.5263158; M = cos^(-1) 0.563158; M = 58.242° = 58° 15`. Answer: The measure of angle M is<span> 58°15`.</span>
Answer:
62 degrees
Step-by-step explanation:
the inside angles of a triangle always equal 180 degrees when added, so i just subtracted 56 and 62 from 180, also, the triangle is isosceles, which has 2 angles of equal value, so the unknown angle had to be equal to 62
