What is the value of x?

21°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

A right angle is 90°.

Therefore, the remaining two angles will be:

= 90°/2 = 45° each.

Therefore, the value of x will be:

2x + 3 = 45

2x = 45 - 3

2x = 42

x = 42/2

x = 21°.

cells do need food. in a process known as cellular respiration, cells convert biochemical energy (oxygen as food) from nutrients into adenosine triphosphate (atp), and then release waste products.
