Given that
HOPE is a parallelogram.
It means,
- OH || FE and HE || PO
Now, HE || PO & HP is transversal.
- So, "y" = 40 ° [ alternate interior angles ]
Now, In triangle HOP
We know, Exterior angle of a triangle is equals to sum of interior opposite angles.
- So, y + z = 70°
It means, 40° + z = 70°
[tex]\longmapsto[/tex]"z" = 70° - 40° = 30°.
Now, OH || FE & HE is transversal.
So, we know, sum of Adjacent angles of a parallelogram is supplementary.
[tex]\rm \longmapsto\:z + 40\degree + x = 180 \degree[/tex]
[tex]\rm \longmapsto\:30\degree + 40\degree + x = 180 \degree[/tex]
[tex]\rm \longmapsto\:70\degree + x = 180 \degree[/tex]
[tex]\rm \longmapsto\:x = 180 \degree - 70\degree[/tex]
[tex]\longmapsto\:\bf{"x"} = 110 \degree [/tex]
Therefore, the measure of the following angle are:
- x = 110°
- y = 40° and
- z = 30°
