Question

solve- find the value of a and b
plzzzzzzzzz​

Answer 1

Step-by-step explanation:

From the given figure

180°-b=70°

b°=180°-70°

b°=110°

4a+18°+2a+12°=180°

6a+30°=180°

6a=180°-30°

6a=150°

a=150/6

a=25°

Answer 2

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Find the value of unknown angles from the given figure.

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

From the figure,

$b = 180 \degree - 70 \degree$

$= 110 \degree$

Also,

$4a + 18 + 2a + 12 = 180\degree$

$\implies6a + 30 \degree = 180 \degree$

$\implies6a = 150 \degree$

$\implies a = 25 \degree$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• $b = 110 \degree \: and \: \: a = 25 \degree$
