PQ⊥PS , m∠QPR=7x−9, m∠RPS=4x+22<br> Find : m∠QPR
emmainna [20.7K]

Given:

It is given that,

PQ ⊥ PS and

∠QPR = 7x-9

∠RPS = 4x+22

To find the value of ∠QPR.

Formula

As per the given problem PR lies between PQ and PS,

So,

∠QPR+∠RPS = 90°

Now,

Putting the values of ∠RPS and ∠QPR we get,

7x-9+4x+22 = 90

or, 11x = 90-22+9

or, 11x = 77

or, x = \frac{77}{11}

or, x = 7

Substituting the value of x = 7 in ∠QPR we get,

∠QPR = 7(7)-9

or, ∠QPR = 40^\circ

Hence,

The value of ∠QPR is 40°.

1. Jasmine drives every morning to her office that is 12 miles from her home
Elanso [62]

Answer:

1. Her time in minutes is 720/s minutes

2. Given her time to be 20 minutes, her speed is 36 mph

Step-by-step explanation:

Mathematically,

Distance = speed * time

In this question, we want to calculate time;

So time = distance/speed

times = 12 miles/s mph = 12/s hours

Now we want our answer in minutes

Kindly recall that 60 minutes = 1 hour

So 12/s hours will be 12/s * 60 = 720/s minutes

2. Since she drives from home to the office in in 20 minutes, we want to calculate her speed in mph

From the time calculated above i.e 720/s

We can equate 20 = 720/s

20s = 720

s = 720/20

s = 36 mph
