On a number line there are six spaces. On the first is the number 2, on the last space is the number 42, on the third space is x
trapecia [35]
1st space is 2
6th space (last) is 42
in betwen that is 5 spaces to go
find distance from 2 to 42
42-2=40

40=5 spaces
divide 5
8=1 space
each space goes upby 8

2=1st space
2+8=2nd space
2+8+8=3rd space=18=x

If cosA=4/5 and cosB=3/5 then find a,b,c
aliya0001 [1]

Answer:

a = 3, b = 4, c = 5

Step-by-step explanation:

Assuming we're working with a right triangle, where c is the hypotenuse, then using the definition of the cosine being the adjacent side over the hypotenuse, then we know:

a = 3, because it is the side adjacent to B

b = 4, because it is the side adjacent to A

c = 5, because it is the denominator in bot fractions

This of course assumes that there is no additional ratio in place.  For example, if the lengths were instead 8, 6 and 10 respectively, then the cosines given would still be 4/5 and 3/5.  Truthfully these only tell relative sizes of the sides, and not their absolute sizes.

Can you please help me I’ll pay you £100
natima [27]

Answer:

The new points to the triangle will be:

A(-6, 6)\\B(-6, 3)\\C(-8, 3)

Step-by-step explanation:

Because the reflection point is at x = -1, all x values will subtract their distances from x = -1 to get their new values. The y values remain the same.

The starting values are:

A(4,6)\\B(4,3)\\C(6,3)

Point A is 5 units away from x = -1, so we'll subtract 5 from -1 to get the new x value: -1 - 5 = -6, so A(-6, 6).

Point B is also 5 unit away from x = -1, so we'll subtract 5 from -1 to get the new x value: -1 - 5 = -6, so B(-6, 3).

Point C is 7 units away from x = -1, so we'll subtract 7 from -1 to get the new x value: -1 - 7 = -8, so C(-8, 3).

Which decimal is larger 36.36 or 36.63 PLEASE HELP!!
Alexeev081 [22]
36.36 is thirty-six and thirty-six hundredths.
36.63 is thirty-six and sixty-three hundredths.

The whole parts are the same. They are both 36.
The decimal parts are 0.63 and 0.36.
Sixty-three hundredths is greater than thirty-six hundredths.
Since 0.63 is greater than 0.36, 36.63 is greater.
