Question

(a) x, 2x, 3x
(b) 8x, 5x, 5x



2. Find the values of x if the three angles of a triangle are:
​

Answer 1

Answer:

x values -

a) 30°

b) 10°

Step-by-step explanation:

By Angle sum property we know that sum of triangle

= 180°

a) x + 2x + 3x = 180°

6x = 180°

x = 180°÷6

x = 30°

b) 8x + 5x + 5x

18x = 180°

x = 180° ÷ 18

x = 10°

Answer 2

Answer:

a)30 b)10

Step-by-step explanation:

a) first we know that the sum of all the anges in triangle is 180°

so x+2x+3x=180°

6x=180°

x=180÷6

x=30°

b) as we discussed above

8x+5x+5x=180°

18x=180°

x=180÷18

hence x=10°

finally the values of x in a,b respectively are 30°,10°
