use tangent.
from the corner y look for the opposite and adjacent sides to your angle.
the opposite side from corner y is 13
the adjacent side from the corner is 4
tanY = 13/4
Y = inverse tangent of 13/4

Answer:
When you join points D(2,3),O(0,0)and E(5,1) which are not collinear it will form a triangle.
Now , Adjacent of ∠ DOE are [ ∠ ODE and ∠OED] .
As we know that Sum of three interior angles of a triangle is 180°.
∠ DOE + ∠OED+∠EDO = 180°
∠DOE=180°- (∠OED+∠EDO)
Supplementary ,of ∠DOE is (∠OED+∠EDO).
Answer:50
Step-by-step explanation:
180-70=(2x-10)+(x+30) 110=3x+20 90=3x x=30 2(30)-10=60-10=<em>50</em>
