Question

I need some help asap its overdue

Answer 1

Angle R = 15°

Angle S = 105°

Angle T = 60°.

Explanation:

The sum of the interior angles of a triangle is 180 degrees. This means that the sum of the three angles in a triangle must equal 180 degrees.

Using this:

We can say that:

x°+7x°+4x°= 180°

Simplify like terms:

12x = 180

Divide both sides by 12

`\sf (12x)/(12)=(180)/(12)`

x = 15°

Now

7x = 7×15° = 105°

4x = 4× 15°=60°

Therefore, Angle R = 15°, Angle S = 105° and Angle T = 60°.

Answer 2

15° , 60° , 105°

Explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles, equate to 180 and solve for x

x + 4x + 7x = 180

12x = 180 ( divide both sides by 12 )

x = 15

4x = 4 × 15 = 60

7x = 7 × 15 = 105

the 3 angle measures are 15°, 60° and 105°
