other angle.​

$\huge\sf\underline{\underline{\green{given}}}$

$\textit{</u></em><em><u>one</u></em><em><u> </u></em><em><u>angle</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>liner</u></em><em><u> </u></em><em><u>pair</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>1</u></em><em><u>4</u></em><em><u>3</u></em><em><u>°</u></em><em><u>}$

$\huge\sf\underline{\underline{\blue{To find}}}$

second angle of this pair

$\huge\sf\underline{\underline{\b</strong><strong>l</strong><strong>u</strong><strong>e</strong><strong>{</strong><strong>sol</strong><strong>ution</strong><strong>}}}$

✰we know that a liner pair makes a angle of -: 180

$\textit{one angle is -: 143°}$

$\textit{let second be'x'}$

$\huge\sf\underline{\underline{\green{Now}}}$

> $\sf\green{x + 143° =. 180}$

>$\sf\green{x = 180° - 143°}$

>$\sf\green{x = 37°}$

$\huge\sf\underline{\underline{\red{AnsWeR}}}$

$\sf\pink{second. angle. is 37°}$

Answer 2

Answer:

The measure of the other angle is 37°.

Step-by-step explanation:

Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Now,

Let, the unknown angle be x.

As we know that the measure of a linear pair is 180°,

x + 143 = 180

x = 180 - 143

x = 37°
