Answer:

Step-by-step explanation:

"three times r" = 3r

"three times r minus ten" = 3r - 10

"product of 5 and the difference of three times r minus ten"

= 5 (3r - 10)

given that r = 4,

the expression becomes

5 (3r - 10)

= 5 [3(4) - 10]

= 5 [12 - 10]

= 5 (2)

= 10

Answer:

$\frac{sin (c)}{AB}=\frac{sin(A)}{26}$

$sin(A)=\frac{26\times sin(13)}{6} =0.97$

$A=sin^{-1}(0.97)=\boxed{77^o}$
