Which term is a perfect square of the root 3x^4?​
Marrrta [24]

Answer:

The perfect square of 3*4 is 9*16

Step-by-step explanation:

A perfect square is a number that can be expressed as the product of two equal integers.

For example 64 is a perfect square because if we multiply 8 two times we will get 64.

Thus the given expression is 3 * 4.

To find perfect square we square the numbers:

3² = 3*3 = 9

4² = 4*4 = 16

Thus the perfect square of 3*4 is 9*16 ....

calculate the angles of a triangle if the angle alpha is 16 ° greater than the angle beta and the angle gamma is 52 ° smaller th
lakkis [162]

Answer:

  • 88°, 72°, 20°

Step-by-step explanation:

<u>Angle alpha is 16° greater than the angle beta:</u>

  • α = β + 16°

<u>Angle gamma is 52° smaller than the beta:</u>

  • γ = β - 52

<u>Sum of angles is 180°, substitute α and β:</u>

  • α + β + γ = 180°
  • β + 16° + β + β - 52° = 180°
  • 3β - 36° = 180°
  • 3β = 216°
  • β = 216°/3
  • β = 72°

<u>Then</u>

  • α = 72° + 16° = 88°
  • γ = 72° - 52° = 20°
