Answer:
Step-by-step explanation:
BC = 15 cm
3x = 15
x = 15/3 = 5
AB =4x = 4*5 = 20 cm
Pythagorean theorem,
AC² = AB² + BC²
= 20² + 15 ²
= 400 + 225
= 625
AC = √625 = 25 cm
AC = 25 cm
Answer:
ok
Step-by-step explanation:
x+7+25+2x+4=180
3x+11+25=180
3x=180-36
3x=144
<em>x</em><em>=</em><em>1</em><em>4</em><em>4</em><em>/</em><em>3</em>
<em>x</em><em>=</em><em>4</em><em>8</em>
