To complete the square (x+2/5)^2 it would be x^2+(4/5)x+4/25
Answer:
∠A=67°
∠B=70°
∠C=43°
Step-by-step explanation:
<u><em>The correct question in English is</em></u>
Determines the measurement of each of the angles of the triangle ABC if it is known that A=(3x+1)°,B=(3x+4)° and C=(2x-1)°.
we know that
The measure of the interior angles in a triangle must be equal to 180 degrees
so
∠A+∠B+∠C=180°
substitute the given values

solve for x



Find the measure of each angle
∠A=(3(22)+1)=67°
∠B=(3(22)+4)=70°
∠C=(2(22)-1)=43°
Answer:picture of question please
Step-by-step explanation:
I think it’s x = 2
-20-12x+10=-34
-10-12x=34
-34+10
-24 divided by 12 = -2
