Question

Find the measure of angle 'a' in each figure. Give reason in each case.
​

Answer 1

Answer:

i. a = 180 -50

= 130

ii. 43 because it is vertically opposite angle .

iii . 209 + 96 + a = 360

= 305 + a = 360

a = 360 - 305

a= 55

iv. 63+ a = 90

a = 90 - 63

a= 27

Answer 2

Step-by-step explanation:

1. as it is supplementary angle

as it is supplementary angle 50+a=180

as it is supplementary angle 50+a=180a=50-180

as it is supplementary angle 50+a=180a=50-180a=130

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically opposite

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43 3. here it is a conjugate angle

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43 3. here it is a conjugate angle209+96+a=360

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43 3. here it is a conjugate angle209+96+a=360305+a=360

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43 3. here it is a conjugate angle209+96+a=360305+a=360a=305-360

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43 3. here it is a conjugate angle209+96+a=360305+a=360a=305-360a=55

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43 3. here it is a conjugate angle209+96+a=360305+a=360a=305-360a=55 4. as it is a right angle

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43 3. here it is a conjugate angle209+96+a=360305+a=360a=305-360a=55 4. as it is a right angle63+a=90

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43 3. here it is a conjugate angle209+96+a=360305+a=360a=305-360a=55 4. as it is a right angle63+a=90a=90-63

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43 3. here it is a conjugate angle209+96+a=360305+a=360a=305-360a=55 4. as it is a right angle63+a=90a=90-63a=27

as it is supplementary angle 50+a=180a=50-180a=130 2. because the given figure is vertically oppositea=43 3. here it is a conjugate angle209+96+a=360305+a=360a=305-360a=55 4. as it is a right angle63+a=90a=90-63a=27 hope it helps
