Question

two angle of angle of a triangle are un ration of 5:6:7. find the measures​

Answer 1

Answer:

answer is 50, 60, 70

Step-by-step explanation:

let each be x

5x : 6x : 7x

as it is triangle the sum of every angle = 180 degree ( i will write it simple 180 )

so - 5x + 6x + 7x = 180 ( i hope you know ration and proportion )

18x = 180  

x = 10

so here (1)  5x = 5*10 = 50 ( 1st angle )

(2)  6x = 6*10 = 60

(3)   7x = 7*10 = 70

so 50, 60, 70

hope it help

Answer 2

consider the 3 given angles of triangle as:

5x , 6x , 7x ..i)

we know sum of all angles of triangle is 180°

thus, 5x+ 6x+ 7x= 180°

18x = 180°

x = 180° / 18

x = 10

now put value of x in.. i )

5x = 5×10 = 50°

6x = 6×10 = 60°

7x = 7× 10 = 70°

this is ur required answer..hope it will help u
