Question

Find the value of a if the measures of the angles of a linear pair are (3a+5) degree and (2a-5) degree. Also draw the figure showing the angles.

Answer 1

$(3a + 5) + (2a - 5) = 180$

$3a + 5 + 2a - 5 = 180$

$5a = 180$

$a = \frac{180}{5}$

$a = {36}^{0}$

$3a + 5$

$3(36) + 5$

$108 + 5$

$113$

$2a - 5$

$2(36) - 5$

$72 - 5$

$67$

Answer 2

Answer:

(3a+5)+(2a−5)=180

3a + 5 + 2a - 5 = 1803a+5+2a−5=180

5a = 1805a=180

a = {180}{5}a=5180

a = {36}^{0}a=360

3a + 53a+5

3(36) + 53(36)+5

108 + 5108+5

113113

2a - 52a−5

2(36) - 52(36)−5

72 - 572−5
