Hey there! :D

1. c - 7 = 32

To solve this problem, add the difference and the subtrahend of the given equation.

32 + 7 = \boxed{\sf 39}

Checking:

To check, simply substitute the conclusion on the unknown quantity.

39 (c) - 7 = 32

Thus, the equation was correct which gives us the answer that:

\large \boxed{ \sf {\: c = 39}}

\begin{gathered} \\ \end{gathered}

2. r + 4 = 39

To solve this problem, subtract the sum and the addend of the given equation.

39 - 4 = \boxed{\sf 35}

Checking:

To check, simply substitute the conclusion on the unknown quantity.

35 (r) + 4 = 39

Thus, the equation was correct which gives us the answer that:

\large\boxed{ \sf {r \: = \: 35}}

Art [367]

Answer:

a.  24\sqrt{3}  and 41.6

b.  52.1

Step-by-step explanation:

a.

Considering the left side triangle the blue dotted side is the side "opposite" to the angle given and the side 24 is the side that is "adjacent" to the angle given. The trigonometric ratio tan relates opposite to adjacent. Also, let the blue dotted side be y.

<u>Note:</u> the exact value of tan 60 is \sqrt{3}

Thus, we can write Tan(60)=\frac{y}{24}\\y=24*Tan(60)\\y=24*\sqrt{3} \\y=24\sqrt{3}

Approximate value (rounded to nearest tenth):  24\sqrt{3} =41.6

b.

Considering the triangle to the right, the side "opposite" to the angle given (53 degrees) is 41.6 (just found in part (a)) and the side "hypotenuse" (side opposite to 90 degree angle) is x. The trigonometric ratio sine relates opposite and hypotenuse.

Thus we can write and solve:

Sin(53)=\frac{41.6}{x}\\x=\frac{41.6}{Sin(53)}=52.1
