Answer:

$T=139$ °

Step-by-step explanation:

First we solve for $x$

Here is our equation

$(21x+13)+(3x-1)+(4x)=180$

$Combine$ $like$ $terms$

$28x+12=180$ °

$28x=168$ °

$x=6$ °

$T=21x+13,T=126+13$

$T=126+13, T=139$

Select the correct answer. For what value of x is sin x = cos 19º, where 0°< x < 90°? OA. 38° ° O B. 71° OC. 26° O D. 19°

Lerok [7]

Answer:

x = 71°

Option B is correct answer.

Step-by-step explanation:

We need to find for what value of x is $sin\: x = cos 19^{\circ}$ , where 0°< x < 90°?

Solving:

$sin\: x = cos\: 19^{\circ}\\Finding \:cos\: 19^{\circ}=0.94551\\Putting\:value:\\sin\:x=0.94551\\Now\:taking\:sin\:inverse\\x=sin^{-1}(0.94551)\\x=71^{\circ}$

So, we get x = 71°

Option B is correct answer.
