Question

ΔPQR ∠P:∠Q:∠R = 5:2:2 then find every angle of ΔPQR

Answer 1

Answer:

here take it...............

Step-by-step explanation:

let the angles be 5x,2x,2x

wkt the sum of all angles of a triangle=180

5x+2x+2x=180

9x=180

x=20.

The angles are 5*20=100,

2*20=40,

2*20=40.

ANSWER:100,40,40.

Answer 2

P=100 degrees

Q=40 degrees

R= 40 degrees

Step-by-step explanation:

suppose a common thing in then is "k"

according to rules :

the addiction of the amounts all angels of a triangle is 180 degrees

so...

P+Q+R=180

5k+2k+2k= 180

9k= 180

k= 180÷9= 20

now....

P= 5k = 5×20= 100

Q= 2k = 2×20 = 40

R = 40
