Question

the angle of a triangle are in the ratio 3:5:7.which type of triangle it is?

Answer 1

Let the angles be in the ratio of x

the ratio is 3x:5x:7x

the sum of all the angles of the triangle is 180°

3x+5x+7x = 180°

15x = 180°

x = 180°/15

x = 12°

measure of 1st angle is 3x = 3(12) = 36°

measure of 2nd angle is 5x = 5(12) = 60°

measure of 3rd angle is 7x = 7(12) = 84°

thus all the angles of the triangle is less than 90°

so the triangle is an ACUTE-ANGLED TRIANGLE and SCALENE TRIANGLE

$Heya \\</p><p>The \: sum \: of \: all \: angles \: of \: a \: triangle \: is \: 180° \\ </p><p>According \: to \: the \: question \\ </p><p>Let \: the \: angles \: be \: 5x, 3x \: and \: 7x \\ </p><p>=> 5x + 3x + 7x = 180° \\ </p><p>=> 15x = 180° \\ </p><p>=> x = 12° \\ </p><p>5x = 5×12 = 60° \\ </p><p>3x = 3×12 = 36° \\ </p><p>7x = 7×12 = 84°$

All angles are less than 90° So it is a acute-angled & scalene traingle...
