Determine the value of x.

B

Step-by-step explanation:

First you have to look at the small triangle and figure out the angle R using the small triangle.

You'd make the triangle into a right angle triangle then using the number you have you'd figure out the angle of R

Round 62.9 to 63 degrees

Angle R and angle S are the same so now you'd move on to the big triangle and make that into a right angle triangle.

The base becomes 3 with an agle of 63 degrees at S.

Now you find the height

base x tan (angle) = height

Round 5.88 to 5.9

And after that continue to find the hypotenuse of the right angle triangle

a² + b² = c²

Since QS and QR are the same lengths, to find x, you'd have to minus the 2.2 from 6.6 to get your answer for x

x = 4.4
