Help ppppppppppppllllllllllllllllsssssssss
iVinArrow [24]

Answer:

The correct option is D ....

Step-by-step explanation:

Angle is ending at the point = (-3, -4)

Signs of both x and y are negative therefore it is in the third quadrant.

To find the the tangent of an angle we have to find  the ratio of the length of the opposite side to the length of the adjacent side.

In this question the opposite side of the angle is of 4 units and the adjacent side of the angle is 3 units.

tanθ = y/x

tanθ = -4/-3

tanθ = 4/3

Thus the correct option is D ....

Jo is thinking of a number. Four less than 9 times the number is 176. Find Jo’s number
kondaur [170]

Answer:

Jo's Number is 20.

Step-by-step explanation:

4 - ( 9 x ? ) = 176.

9 x 20 = 180.

9 x 20 = 180, then subtract 180 by 4.

180 - 4 = 176.

Therefore, Jo's number is 20.

Given that S is the centroid of triangle MNO, find SQ.
AnnZ [28]

Answer:

|SQ|=5

Step-by-step explanation:

If S is the median, then OP is a median of triangle OMN.

This implies that:

|MP|=|NP|

3x-4=x+4

We group like terms and solve for x.

3x-x=4+4

\implies 2x=8

\implies x=4

Now we know that: MN:SQ=2:1

But MN=2x+2

This implies that:

2x+2:SQ=2:1

Put x=4

2(4)+2:SQ=2:1

10:SQ=2:1

Therefore |SQ|=5
