In one triangle one of the angles is four times the measure of another and the third angle is five times as much as that angle what are the measurements of all three angles

The measurement of all three angles of Triangle are 18°  ,72°  ,90°

Step-by-step explanation:

Given as in a Triangle :

Let The angles of triangle are ∠A , ∠B , ∠C

From The property of Triangle.

The sum of measure of all the three angles of Triangle = 180°

So , ∠A + ∠B + ∠C =  180°

Now, According to question

∠A = 4 × ∠B

∠C = 5 × ∠B

∵ ∠A + ∠B + ∠C =  180°

Or, 4 × ∠B + ∠B + 5 × ∠B = 180°

Or, 10 × ∠B = 180°

∴   ∠B = = 18°

So,    ∠B = 18°

And  ∠A = 4 × 18° = 72°

        ∠C = 5 × 18° = 90°

Hence The measurement of all three angles of Triangle are 18°  ,72°  ,90° Answer  

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
