Question

The three angles of a triangle are in the ratio 1:2:3. find all the angles of the triangle . name the type of triangle​

Answer 1

$\huge{\mathfrak{\underline{\red{answer}}}}</p><p>$

Sum of angles of a triangle = 180°

Three angles of the triangle = 1x, 2x, 3x

so,

1x + 2x + 3x = 180

6x = 180

x = 180/6

x = 30

second angle = 2x = 2(30) = 60°

Third angle = 3x = 3(30) = 90°

.

.

Type of triangle-

The triangle is a Right angles triangle

because one angle is of 90°

Answer 2

Answer:

let three angle be x,2x,3x

Step-by-step explanation:

sum of triangle =180°

x+2x+3x=180°

6x=180°

x=180°/6

x=30°

so,

first angle=x

=30°

second angle=2x

= 2×30°

= 60°

third angle=3x

= 3×30°

=90°

it is a right angle triangle because the third angle is 90° so name of this triangle is right angle triangle

thankyou
