The three inside angles (a, b and c) of a right-angled triangle are in the ratio 7: 18: 11 the smallest angle is 35 degrees work out angles a, b and c

Therefore the measure of the angles of a right angled triangle ABC are,

Step-by-step explanation:

Let the Common multiple be  ' x '

given the angles are in the ratio 7 : 18 : 11

Therefore the angles are

∠A = 7x , ∠B = 18x  , ∠C = 11x

To Find:

∠A = ? , ∠B = ? , ∠C =?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

  ..Triangle sum property.

Substituting the values we get

substitute ' x ' in the measure angles we get

Therefore the measure of the angles of a right angled triangle ABC are,

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.
