Answer:

∠A=67°

∠B=70°

∠C=43°

Explanation:

The correct question in English is

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


(3x+1)\°+(3x+4)\°+(2x-1)\°=180\°

solve for x


(8x+4)\°=180\°


8x=180-4


x=22

Find the measure of each angle

∠A=(3(22)+1)=67°

∠B=(3(22)+4)=70°

∠C=(2(22)-1)=43°
