Question

I need to find what x is

Answer 1

x = 60°

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°

Answer 2

________________________________

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

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

________________________________

step 1:

`y = 33</strong><strong>⁰</strong><strong> + 87</strong><strong>⁰</strong><strong>`

reason:

exterior angle is =sum of interior angles

________________________________

step 2:

`y = 120</strong><strong>⁰</strong><strong>✓</strong><strong>`

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:

`120</strong><strong>⁰</strong><strong> + x = 180</strong><strong>⁰</strong><strong>`

Write value of y ie 120

________________________________

step 3:

`x = 180</strong><strong>⁰</strong><strong> - 120</strong><strong>⁰</strong><strong>`

take 120⁰ to other side to subtract it with 180⁰

________________________________

step 4:

`x = 60</strong><strong>⁰</strong><strong>✓</strong><strong>`

________________________________

⚡ Final answer:

x=60⁰✓
