Step-by-step explanation:
cuz all the other options sum up to 180 except A it sum up to 181
and the sum of angle in triangle is equal to 180°
Step 1: Add together the known angles.
Step 2: Subtract the sum from 180°.
Answer:
k=3 z=-6
Step-by-step explanation:
12k=36
k=36/12
k=3
-6z=36
z=36/-6
z=-6
12(3)-6(-6)=36
180=(9X-11)+(4X+1)+(7X-3)
180=20x-13
193=20x
9.65=x
