<u>Final Answer:</u>
x = 20
<u>Step-by-step explanation:</u>
we'll be using the pythagorean theorem method, in this triangle the missing letter is a.
formula: 
a = x
b = 21
c = 29
a = 
a = 
(note: 29² = 29 × 29 = 841 and 21² = 21 × 21 = 441)
a = 
a = 20
x = 20
Change your percents to decimals, then multiply 100 by your 12% decimal, then multiply 79.74 by your 7.25% and you should get the answer
1.3+-2.4= -1.1 hope I helped :)
