Determine the length of x in the triangle. Give your answer to two decimal places. You may use the Desmos scientific calculator:

35.09

Step-by-step explanation:

From the question given above, the following data were:

Opposite = 12

Hypothenus = X

Angle θ = 20 °

The value of x can be obtained by using sine ratio as illustrated below:

Sine θ = Opposite / Hypothenus

Sine 20 = 12 / X

0.342 = 12 / X

Cross multiply

0.342 × X = 12

Divide both side by 0.342

X = 12 / 0.342

X = 35.09

Thus, the value of X is 35.09

answer: i don't understand it

step-by-step explanation: sorry

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
