Question

*PLS HELP*
I need help on this and please provide an explanation
​

Answer 1

• The value of x is 9.

Explanation:

We know that:

• 46 + (5x - 1) = Complementary angles = 90°

Solution:

• 46 + (5x - 1) = 90°

Removal of brackets:

• => 46 + 5x - 1 = 90
• => 45 + 5x = 90

Subtracting 45 from both sides:

• => -45 + 45 + 5x = 90 - 45

Solving:

• => 5x = 45
• => x = 9

Hence, the value of x is 9.

Answer 2

x = 9

Explanation:

To Find:-

• Value of x

Given:-

• 46° and (5x - 1)° are complementary angles

Solution:-

As we know,

Complementary angles:

The angles whose sum results to 90° are known as the complementary angles.

So,

46° + (5x - 1)° = 90°

• [Since complementary angles]

=> 46 + 5x - 1 = 90

• [On Simplification]

=> 45 + 5x = 90

• [On subtracting both sides with 45]

=> 45 + 5x - 45 = 90 - 45

• [On Simplification]

=> 5x = 45

• [On dividing both sides with 5]

`= > (5x)/(5) = (45)/(5)`

• [On Simplification]

=> x = 9

Hence, required value of x = 9 (Ans)
