Answer: p:a


Step-by-step explanation:

Triangle ABC is similar to triangle PQR. In similar triangles sides are in proportion.The side opposite to equal angles are in proportion.

r is opposite to <R and c is opposite to <C in figure .These angles C and R are marked equal in the triangles.So the sides are in proportion  .Among the given options p and a sides are opposite to the equal angles <P and <A.so they will be in proportion.

r:c=p:a.

Simultaneous equations <br>3x + 2y= 13<br>x + 2y= -1
antoniya [11.8K]

Answer:

{x = 7  , y = -4

Step-by-step explanation:

Solve the following system:

{3 x + 2 y = 13 | (equation 1)

{x + 2 y = -1 | (equation 2)

Subtract 1/3 × (equation 1) from equation 2:

{3 x + 2 y = 13 | (equation 1)

{0 x+(4 y)/3 = (-16)/3 | (equation 2)

Multiply equation 2 by 3/4:

{3 x + 2 y = 13 | (equation 1)

{0 x+y = -4 | (equation 2)

Subtract 2 × (equation 2) from equation 1:

{3 x+0 y = 21 | (equation 1)

{0 x+y = -4 | (equation 2)

Divide equation 1 by 3:

{x+0 y = 7 | (equation 1)

{0 x+y = -4 | (equation 2)

Collect results:

Answer:  {x = 7  , y = -4

If on the unit circle C, the distance from P(1, 0) to the point T ( 4/5 , 3/5 ) is x, determine the coordinates of the point at
AveGali [126]

Answer:

(\frac{4}{5}, -\frac{3}{5}  )

Step-by-step explanation:

The point P(1,0) and T(\frac{4}{5}, \frac{3}{5}  ) are on the unit circle C and the arc length from P to T is x.

Let us assume that point P - x i.e. the point obtained by moving clock wise direction along the circle from P is T'.

Because of the symmetry of the circle about the coordinate axes, the x-coordinate of point T' will be \frac{4}{5} and the y-coordinate will be -\frac{3}{5}.

So, coordinates of T' are (\frac{4}{5}, -\frac{3}{5}  ).

Here we must notice that point T' is the reflection point of T with respect to X-axis. (Answer)
