Answer:
m∠LTE = 110
Step-by-step explanation:
1. add up all of the arcs.
2x+3x+4x-8+x-12
2. all of the arcs equal 360
2x+3x+4x-8+x-12=360
3. Find x
10x-20=360, x=38
4. angle LTE is equal to half of the sum of the intercepted arcs.
0.5(arc LE +GF)
5. plug in LE +GF with x
.5(76+144)
So if the exterior angle is 130°, then the inner angle is 50°.
The total of the inner angles of a triangle is (n-2)180°=180°, so 180°-50°=130°
With the remaining two angles =130° and they are both in the ratio of 2:3, one angle has a measure of 52° and 78°.
Thus the measure of the largest angle is 78°.
