Using Triangle sum theorem you add all the angles to make 180. So 47.7+51.1+<1=180
98.8+<1=180
-98.8 -98.8
<1= 81.2
The linear equation would be, 5d + 3h + 8s = 231
The first thing we must do for this case is find the scale factor.
We have then that for the larger side of both triangle, the scale factor is:
![k = 0.6](https://tex.z-dn.net/?f=k%20%3D%200.6)
To find the other two sides, we must apply the scale factor on each side of the triangle FGH.
We have then:
For PQ
For QR
Answer:
You have that the lengths for the other two sides of triangle PQR are:
W=93
since triangle is 180
180-142=38
180-38-49=93
