In the given figure , if angel ROQ = 90 and angel POS : angel ROS = 4 : 5 , then the value of angel SOQ is 

In The Given Figure If Angel ROQ 90 And Angel POS Angel ROS 4 5 Then The Value Of Angel SOQ Is class=

Sagot :

First of all, these are angles.  'Angels' don't pop up too often in math.

ROQ is 90°.

Then POR is also 90°.

POS : ROS = 4 : 5

So if you split up POR into (4 + 5) = 9 pieces, POS is 4 of them and ROS is 5 of them.  

Since POR is 90°, each piece is 10° .

POS = 40°
and
ROS = 50° .

SOQ is ROS added onto ROQ.

ROQ = 90°
ROS = 50°
------------------
SOQ = 140°
