Step-by-step explanation:

To find the largest angle in ∆IJK we must first find the unknown variable which is v.

Angles in a triangle add up to 180.

To find v, add up all the angles and equate them to 180°

That's

36v + 17v + v + 72= 180

54v = 180 - 72

54v = 108

Divide both sides by 54

v = 2

Now substitute the value of v into the above expressions in the triangle

That's

17v = 17(2) = 34°

36v = 36(2) = 72°

v + 72 = 2 + 72 = 74°

From the above solution the largest angle for ∆IJK is 74°
