Answer:
Step-by-step explanation:
Here two triangles are given to us , which are attached to each other . Here we can use the concept of<u> </u><u>Trigonometry</u> to find out the value of x. The angles of the triangle are 60° and 45° . Let the common side be p .
Step 1: <u>Use </u><u>the </u><u>ratio </u><u>of </u><u>tan </u><u>in </u><u>upper</u><u> </u><u>triangle</u>
Substitute the respective values ,
Cross multiply ,
Step 2: <u>Use </u><u>the </u><u>ratio</u><u> of</u><u> </u><u>cos </u><u>in </u><u>lower </u><u>tr</u><u>i</u><u>angle</u>
Substitute the respective values ,
Cross multiply ,
Put the approximate values of √2 and √3
This equals to ,
<u>Hence</u><u> the</u><u> </u><u>va</u><u>l</u><u>ue </u><u>of </u><u>x </u><u>is </u><u>8</u><u>.</u><u>5</u><u>7</u><u> </u><u> </u><u>.</u>
