The value of t = 2. <u>Option a)</u> 2 is the correct answer.
<u>Step-by-step explanation:</u>
Perimeter is the sum of three sides of a triangle.
Given that, the points D and E are midpoints of the sides.
Therefore,
side AB= AD+DB
AB= 3t + 3t = 6t
side BC= BE+EC
BC= 4t + 4t = 8t
side AC= 7t+6
Perimeter of the triangle= sum of (side AB+side BC+side AC)
48 = 6t+8t+7t+6
48 = 21t+6
t= 42/21
t= 2

Answer:
500 meters
Step-by-step explanation:
1km=1000meters so 0.5km=500m
m<SMJ + m<SME = 180° <em>(Linear pair) ⇒ </em>m<SMJ + 59° = 180° ⇒ m<SMJ = 121°
m<MJS ≅ m<EJA: <E + <A + <J = 180° ⇒ 90° + 48° + <J = 180° ⇒ <J = 42°
<u>m<JSM + m<SMJ + m<MJS = 180° </u><u><em> (Triangle sum) </em></u>
m<JSM + 121° + 42° = 180°
m<JSM + 163° = 180°
m<JSM = 17°
Answer: 17°
