Answer:
7
Step-by-step explanation:
Comparing the two similar triangles
JK/MN = JL/MP
25/30 = 20/(4X - 4)
CROSS MULTIPLY
25(4X - 4) = 30 × 20
100X - 100 = 600
COLLECTING LIKE TERMS
100X = 600 + 100
100X = 700
DIVIDING THROUGH BY 100
X = 700/100
X = 7
k
width = 115 cm
width² = 277² - 252²
width² = 76729 - 63504 = 13225
