Answer:
Step-by-step explanation:
Sum of 3 angles of triangle= 180
147 + 4x + x = 180
147 +5x = 180
5x = 180 - 147
5x = 33
x = 33/5
x = 6•6 (Answer)
Answer:
$160
Step-by-step explanation:
Simple interest=principal×time×rate/100
Principal=$800
Time=5years
Rate=4%
S.I=800×5×4/100
S.I=8×4×5
S.I=160
So the simple interest is $160
