Step-by-step explanation:
we know that
The circumference of a circle is equal to

in this problem

substitute
-----> exact value of the circumference
Find the approximate value of the circumference
assume

Answer:
m<FLS=108 degrees
m<SLT=72 degrees
m<ALG=18 degrees
Step-by-step explanation:
(3x) + (4x +12) = 180
x = 24
4x + 12 = 108 = m<FLS
180 - 108 = 72 = m<SLT
SLG = 72 + 90 + x
x = 18 = m<ALG
At 2 minutes, the heart would beat 140 times.
700/10=70
140/70=2
