The three angles the three angles of a triangle are in the ratio 6:3: 1 find all the angles of a triangle
Answers
Answer:The measures of the angles of a triangle are in the ratio of 1:3:6. ... Let the smaller angle be = to x, then x + 3x + 6x = 180. Combining like terms yields 10x = 180. Therefore, x = 18 degrees, 3x = 3(18) or 54 degrees, and 6x = 6(18) or 108 degrees.
Step-by-step explanation:
. ratio of angles of triangle = 6:3:1
. Measure of all angles of triangle
Let the all angles of triangle are as :-
6x°, 3x° and 1x°
Now,
We know that, according to a property of triangle, sum of interior angles of triangle is equal to 180°
So,
by this property of triangle, we can say that 6x°+3x°+1x° = 180°
Let solve it =>
6x°+3x°+1x° = 180°
=> 10x° = 180°
=> x = 180/10
=> x = 18°
By solving this , we foun that the value of x = 18°
Hence,
We can find the measure of all angles of triangle by putting the value of x in its unknown angles.
Let's put the value of x in 6x°+3x°+1x°
. 6x°
=> 6 × 18° = 108°
. 3x°
=> 3×18 = 54
. 1x
=> 1x° ×18 = 18°
Hence,
The measure of all angles of triangle are as :--
108°, 54° and 18°
to verify our statement, We have to add all angles of triangle equate it by 180° and have to make LHS = RHS
108°+54°+18° = 180°
=> 162°+18° = 180°
=> 180° = 180°
LHS = RHS
hence, verified
