Encuentren dos números cuyo cociente sea -1 y que la resta del primero menos el segundo sea -3/2
miskamm [114]

Answer:

\dfrac{3}{4}\ \text{and}\ \dfrac{-3}{4}

Step-by-step explanation:

Find two numbers whose quotient is -1 and the subtraction of the first minus the second is -3/2

Let two numbers are x and y. When they are divided the quotient is -1. So,

\dfrac{x}{y}=-1

It can also be written as :

x = -y ....(1)

The subtraction of first minus the second is -3/2 .

x-y=\dfrac{-3}{2}\ .....(2)

Use equation (1) in (2),

-y-y=\dfrac{-3}{2}\\\\-2y=\dfrac{-3}{2}\\\\y=\dfrac{3}{4}

From equation (1) : x=\dfrac{-3}{4}

Hence, two numbers are \dfrac{3}{4}\ \text{and}\ \dfrac{-3}{4}.

Triangle QST  is similar to triangle PQR

We are given that measure of angle SRP is 90°

Q is the point of the hypotenuse SP

Segment QR is perpendicular to PS and T is a point outside the triangle on the left of s

We need to find which triangle is similar to triangle PQR

So,

Using Angle - Angle - Angle Criterion We can say that

m∠PQR = m∠SQR  (AAA similarity)

m∠SQR=m∠SQT (AAA similarity)

Where m∠Q =90°  in ΔQST and PQR

Therefore ΔQST is similar to ΔPQR
