Since the exterior angle and other angle must be complimentary the angle in the triangle must be 60°. Since it’s a right triangle one angle must be 90°. A triangle must add up to 180°. 60°+90°=150°. 180°-150°=30°. So your angles in the triangle would be 60°, 90°, and 30°

Doss [256]

Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The perimeter of the rectangle will be : 2\times(\ length+width)

The perimeter will be : 2 \times(2x+3x+3)

The perimeter will be : 10x+6

As per given question, the perimeter is given as 146 unit.

So,

10x+6=146

Subtracting 6 on both sides

10x=140

x=14

Plugging the value x in sides, the sides will be 2 \times 14=28 and

3 \times 14+3=45

Hence the length of the longer side is 45 units.   :   Answer

Hope it will help :)
