Answer:
1. so the numbers are 8 and 3. If it helps please mark it brainliest.
2. It is given that the angle of triangle are in the ratio 2 : 3 : 4. Let the angles are 2x, 3x and 4x.
According to the angle sum property, the sum of interior angles of a triangle is 180 degree.
2x+3x+4x=1802x+3x+4x=180
9x=1809x=180
x=20x=20
The value of x is 20.
2x=2(20)=402x=2(20)=40
3x=3(20)=603x=3(20)=60
4x=4(20)=804x=4(20)=80
Therefore the angles of triangle are 40, 60 and 80.
3. The two positive integers are 20 and 60 respectively
Step-by-step explanation:
Let the non zero constant be x.
Then according to the ratio 1:3, And the second number be = 3x
= Let the first number be = 1x or x
ATP,
=>3x-x=40
=>2x=40
=>x=40/2
=>x=20
therefore, first positive integer= x= 20
Second positive integer= 3x= 3 x 20= 60
