Step-by-step explanation:
If the figure is triangle then,
Let PR be x
So,
PQ+QR+PR= 180 (Sum of all the angles of the triangle)
Therefore,
6x+25+16-3x+x=180
4x+36=180
4x= 180/36
x= 144/4
X= 36
NOW,
PQ= 6x+25
= 6(36)+25
= 216+25 = 241= PQ.
QR = 16-3x
= 16-3(36)
= 16-108
= -92
PR = 36
hope it helps

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is one leg
- b is another leg
- c is hypotenuse
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
a = 19
b = <em>x</em>
c = 21
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: 19² + x² = 21²
- Isolate <em>x</em> term: x² = 21² - 19²
- Exponents: x² = 441 - 361
- Subtract: x² = 80
- Isolate <em>x</em>: x = √80
- Simplify: x = 4√5
