Question

1. Find the measures of the numbered angles in each rectangle.​

Answer 1

Answer:

we know,

every angle of Rectangle is 90°

hence,

58+4th angle = 90

4th angle = 90-58

4th = 32°

as well as

5th & 3rd angle is also measured as 90°

Now their are 2 ∆ formed

hence we can say that,

90+58+ 1st angle = 180°

1st angle = 180°-90-58

= 180°- 148°

1st angle = 32°

thus, in another∆ we can say that,

32+90+2nd angle = 180°

2nd angle = 180-32-90

= 180- 122

2nd angle = 58°
