Question

The angles of triangle are (x + 10°), (2x – 30°) and x°. Find the value of x.

Answer 1

Answer:

50

Step-by-step explanation:

Angles:

x+10

2x-30

x

Angle sum property: the sum of all angles of a triangle is 180 degrees.

So,

(x+10)+(2x-30)+(x)=180

x+10+2x-30+x=180

4x-20=180

4x=200

x=50

Hence the angles are:

60 degrees

70 degrees

50 degrees

Answer 2

Answer:

❥We know that sum of all the angles of a triangle is 180°.

So,

=>(x+10°)+(2x-30°)+x=180°

=>x+2x+x=180°-10°+30°

=>4x=200°

=>x=200/4

=>x=50°

Other angles:-

• (x+10°)

=>50°+10°=60°

• (2x-30°)

=>(2×50°)-30°

=>100°-30°=70°

❥To verify:-

Simply add all the angles=>50°+60°+70°=180°

❥Hope it helps you..
