Answer:
α ≈ 76°
Step-by-step explanation:
The vertices of a rectangle are right , that is 90°
Using the tangent ratio in right triangle ABC
tanα = = = = 4, then
α = (4) ≈ 76° ( to the nearest degree )
Answer:
ans A and B is correct may be
Answer:
hi
x+102° =180°[ Being cointerior angle]
x=180°-102°
x=78°
Also,
y=102°[ the opposite angle of parallelogram are equal]
z=78°[ the opposite of parallelogram are equal]
Hence, x=78°,y=102° and z=78°
