Answer:

hence <A =41°

Step-by-step explanation:

x + 6 + 2x + 5 + 2x - 6 = 180  \\  (sum \: of \: inside \: the \: triangle \: is \: 180) \\ 5x + 5 = 180  \\ 5x = 180 - 5 \\ x =  \frac{175}{5 }  \\ x = 35 \\ now \: putting \: the \: value \: of \: x \: in \: ange \: a \\  < a = x + 6 \\  < a = 35 + 6 \\  < a = 41

What is the length of side c
Nutka1998 [239]

c ≈ 16.7 ( to 1 dec. place ) → d

since triangle ABC is right use the cosine ratio to find c

cos33° = \frac{adjacent}{hypotenuse} = \frac{14}{c}

multiply both sides by c

c × cos33° = 14 ( divide both sides by cos33° )

x = \frac{14}{cos33} ≈ 16.7 ( to 1 dec. place )

Is C + 11 = 20; c =9 a solution if the equation
Deffense [45]

Answer:

Step-by-step explanation:

c + 11 = 20....subtract 11 from both sides

c = 20 - 11

c = 9

and u know that u can check ur answer by subbing it back into the equation

c + 11 = 20

9 + 11 = 20

20 = 20 (correct)

so yes, ur answer c = 9 is correct
