Answer 1

________________________________

$\small{\purple {\sf \underline{Part 1:}}}$

$\small{\purple {\sf \underline{To \: find\:y:}}}$

________________________________

step 1:

$y = 33⁰ + 87⁰$

reason:

exterior angle is =sum of interior angles

________________________________

step 2:

$y = 120⁰✓$

after adding 33⁰ and 87⁰ we get 120⁰

________________________________

$\small{\purple {\sf \underline{Part 2:}}}$

$\small{\purple {\sf \underline{To \: find\:x:}}}$

________________________________

step 1:

$x + y = {180}^{0}$

reason:

leaner pear

________________________________

step 2:

$120⁰ + x = 180⁰$

Write value of y ie 120

________________________________

step 3:

$x = 180⁰ - 120⁰$

take 120⁰ to other side to subtract it with 180⁰

________________________________

step 4:

$x = 60⁰✓$

________________________________

⚡ Final answer:

x=60⁰✓

hope it helped you:D

have a cheerful day!

Answer 2

Answer:

x = 60°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180 for x

x = 180° - (87 + 33)° = 180° - 120° = 60°
