Question

Find x and ray
Please answer

Answer 1

Answer:

In triangle PQR

60°+70°+y=180°

130°+y=180°

180°-130°=y

50°=y

x=50°

Answer 2

Answer:

x= 130°

y=50°

Step-by-step explanation:

If the triangle's two corner's angle is given then, First sum the two angles and find the difference between the 180° and the sum.

y = 180° - ( 70°+60°)

= 180° - 130°

= 50°

If we have a linear pair, the one side's angle we already found out that it is 50° then, find difference between 180° and the other angle i.e. 50° .

x = 180° - 50°

= 130°

In case , you don't know about linear pair then, it is when two adjacent angles form a linear pair if their two non - common arms form a straight line.
