Question

14. Coefficient of x' in 3x-5 is
15. The angles of triangle are in the ratio 3:2:7. The measure of each of its angles are​

Answer 1

Answer:

Step-by-step explanation:

1) coefficient is 3 ..

2)We know that the sum of angles of a triangle is 180 degrees ( AMS property )

So ,

if we consider "x" as the unknown angle  

then we get

3x + 2x + 7x = 180

12x = 180

x= 15 degrees

so the angles of the triangles are

3x=3(15)=    45 degrees

2x=2(15)=    30 degrees

7x=7(15)=  105 degree

hope it helps..mark me as brainliest..if this was helpful

Answer 2

Answer:

may be my answer helps you

Step-by-step explanation:

The angles of a triangle are x,2x,3x.

Sum of angles of the triangle is 180

o

Thus, x+2x+3x=180

o

⟹6x=180

⟹x=

6

180

⟹x=30

As x=30

The angles of the triangle are, 30

o

,60

o

and 90

o

Since, one of the angles of the triangle is 90

o

. It is a right angled triangle.

Since, all the angles of the triangle are different, Hence all the sides of the triangle will be different. Hence, it is a right angled scalene triangle.
