EXPLANATION
The given triangle has a right angle.
The side opposite to the 45° angle is 7 units.
To find angle x, we use the tangent ratio.
Recall the mnemonics TOA, which means,




To find y, we use the sine ratio, which means






Highest number - lowest number = 8-3 = 5
I hope that helps and best of wishes !!
I think it’s the quadratic trinomial because a trinomial has three terms and the problem has the terms.
