1.	In figure, if I \|\| m and ∠1 = (a + 3b+10)°, ∠4 = (2a + b)° and ∠5 = (3b + 20)°. Find a and b
Answer» ANSWER: here is UR answer hope u have been understood Step-by-step explanation: As l is PARALLEL to m and t is a transversal. ∴a=132 o .... Corresponding angles ANd b=1320 o .. vertically opposite angles Now, ⇒2a+b=2×132 o +132 o ⇒264 o +132 o =396 o hope it was HELPFUL

here is UR answer hope u have been understood

Step-by-step explanation:

As l is PARALLEL to m and t is a transversal.

∴a=132

.... Corresponding angles

ANd b=1320

.. vertically opposite angles

Now,

⇒2a+b=2×132

+132

⇒264

+132

=396
