Question

7. Find the values of the unknowns and y and x in the following diagrams:​

Answer 1

Step-by-step explanation:

y+ 105⁰= 180⁰

y= 180⁰-105⁰

y=75⁰

40⁰+75⁰+x= 180⁰

x= 180⁰- 40⁰-75⁰

x= 180⁰- 115⁰

x= 65⁰

Answer 2

Answer:

for value of y :-

for straight line value of angle is 180°

so,

y+105° = 180°

y = 180°- 105°

y = 75°

for value of x :-

the sum of angles in a triangle is equal to 180°

now,

40° + y + x = 180°

40° + 75° + x = 180°

115° + x = 180°

x = 180° - 115°

x = 65°
