4.  Of the three angles of a triangle, the second one is one third of the first and the third angle is 26 degrees more than the first angle. Find all the three angles of the triangle.

5.  If one number is multiplied by the Number the resulting number is the sum of the square of the first number and cube root of the second number. Find the number of such Pairs. ​

Answer 1

Answer:

Answer 3: 29 and 31. So the twin primes are 29 and 31

Answer 4: Let angles of triangle are x, y and z deg. respectively.

Y=1/3z =1/3*1.5x

and z=1.5x.

Sum of all three angles x+y+z =180°

x+1/3*3/2x+1.5x=180°

x+1/2x+3/2x=180°

3*x=180°

x=60°, y=30° , z=90

Answer 5:2, 3, 4,5 are such numbers.
