Answer 1

Answer:

$\huge\rm\red{AnsWer:}$

$\bf\green{given:}$

In ∆ ABC

• angle A = 3x
• angle B = 2x
• angle C = x

$\bf\green{to\:find}$

• measure of x = ?

By angle sum property

sum of all angles of triangle = 180°

➡️ 3x + 2x + x = 180°

➡️ 6x = 180°

➡️ x = 180/6

➡️ x = 30

Answer 2

Given:

A triangle with

• 1st angle = x
• 2nd angle = 2x
• 3rd angle = 3x

To Find:

The 1st angle that is x of the triangle.

How To Find:

To find the angles of the triangle we will use the property that is $\sf{\boxed{Sum\:of\:interior\:angles\:of\:triangle= 180^\circ}}$ and substitute the value and solve.

Solution:

Using the property,

⇒ Sum of interior angles of triangle = 180°

Substitute the values,

⇒ x + 2x + 3x = 180°

Add the terms in LHS,

⇒ 6x = 180°

Take 6 to RHS,

⇒ x = $\dfrac{180}{6}$

Divide 180 by 6,

⇒ x = 30°

Now substitute the value.

• 1st angle = x = 30°
• 2nd angle = 2x = 2(30) = 60°
• 3rd angle = 3x = 3(30) = 90°

∴ Therefore the value of x is 30°.

Property Used:

• Sum of interior angles of triangle = 180°
