In triangle PQR, Line QS and line SR are angle bisectors to angle P (74 degrees). How many Degrees are in the angle QSR.

AlexFokin [52]

we know that

in the triangle PQR

m∠PQR+m∠QPR+m∠QRP=180°------> the sum of the internal angles of a triangle is equal to 180 degrees

(m∠PQR+m∠QRP)+74°=180°-------> (m∠PQR+m∠QRP)=106°

we know that

If QS and SR are angle bisectors

then

In the triangle QSR

m∠SQR+m∠QSR+m∠QRS=180°-------> equation 1

and

(m∠SQR+m∠QRS)=106°/2--------> (m∠SQR+m∠QRS)=53°

substitute the value of (m∠SQR+m∠QRS)=53° in the equation 1

53°+m∠QSR=180°

m∠QSR=180°-53°-------->m∠QSR= 27°

therefore

the answer is

The measure of angle QSR is 27 degrees

aleksley [76]

Answer:

The original price of the laptop was US$ 875

Step-by-step explanation:

1. Let's review all the information given for solving this question:

Sale price of the laptop = US$ 525

Discount from the original price = 40%

2. Let's find the original price of the laptop

Original price of the laptop = x

Sale price of the laptop = US$ 525

Sale price of the laptop = x - 40%x

525 = x - 0.4x

525 = x - 4x/10 (0.4 = 4/10)

5,250 = 10x -4x (Multiplying by 10 at both sides)

5,250 = 6x

5,250/6 = 6x/6 (Dividing by 6 at both sides)

875 = 6

The original price of the laptop was US$ 875
