Find the value of x.

alukav5142 [94]

Step-by-step explanation:

The sum of the three angles in a triangle must be $180$ . Since this triangle has a right angle, we know that it is $90$ °, so the sum of the remaining two angles must be $90$ .

We can set up an equation for the two remaining angles to determine the value of $x$ :

$(x + 28) + x = 90$

$2x + 28 = 90$

$2x = 62$

$x = 31$

Pls guys help me pls :c

Answer: A. $x\geq21\dfrac{2}{3}$ .

Step-by-step explanation:

The given inequation: $81-1\dfrac{1}{5}x\leq55$

$\Rightarrow\ 81-\dfrac{6}{5}x\leq55$

Multiplying 5 on both the sides, we get

$5(81-\dfrac{6}{5}x)\leq5\times55\\\\\Rightarrow\ 405-6x\leq275\\\\\Rightarrow\ 6x\geq405-275\\\\\Rightarrow\ 6x\geq130\\\\\Rightarrow\ x\geq\dfrac{130}{6}\\\\\Rightarrow\ x\geq\dfrac{65}{3}\\\\\Rightarrow\ x\geq21\dfrac{2}{3}$

Hence, the inequality for x is $x\geq21\dfrac{2}{3}$ .

So, the correct option is A. $x\geq21\dfrac{2}{3}$ ..
