Question

у 7. The angles of a triangle are in the ratio 3:4:5. Find the measure of each angle. ​

Answer 1

Answer:

3x =45, 4x=60 ,6x= 75

Step-by-step explanation:

3x+4x+5x=180 [angle sum property of a triangle]

12x=180

x=180/12

x= 15

3x=3×15=45

4x=4×15=60

5x=5×15=75

45+60+75=180

this is the final answer 3x=45

4x=60

5x=75

Answer 2

Step-by-step explanation:

Let the angles of 5 the triangle be:x

Then,3x,4x,5x

We know that the Sum all angles of triangle is 180

so,3x+4x+5x=180

→12x=180

→x=180/12= 15

Hence,the first angle measure(15X3)=45°,second angle measure(15X4)=60°and third angle measure (15X5)=75°.
