The equation that can be used to solve for m∠C is 22° + m∠C = 90°.

To solve for m∠C, you can start by subtracting 22° from both sides of the equation:

22° + m∠C - 22° = 90° - 22°

This simplifies to:

m∠C = 68°

So, m∠C is equal to 68°.

can u rewrite this like a 12 year old but keep it formal

Sure! To find the measure of angle C, you can use the equation 22° + m∠C = 90°. To solve for m∠C, you take away 22° from both sides of the equation. This gives you m∠C = 68°. So, the measure of angle C is 68°.
