What is the value of t rounded to the nearest tenth

12.4
10.2
8.9
6.4

6.4

Step-by-step explanation:

Find measurement of leg using pythagorean theorem  

b^2 = c^2- a^2

b^2= 13^2 - 4^2

b^2= 169-16

b^2= 153

b= 12.4

t+6= 12.4

subtract 6 from both sides

t= 6.4

r and t.

both are 64 degrees.

are ya tryin to ask something or is this a statement
