We know that
applying the law of cosines
a² = b²+ c²<span> – 2*b*c*cos(A)
</span>
in this problem
a=?
b=20
c=9
A=90°
so
a² = b²+ c² – 2*b*c*cos(A)
but
cos (A)=0
a² = b²+ c²-----> 20²+9²----> a²=400+81----> a²=481-----> a=√481
a=21.93-----> a=22
the answer is
22
Answer:
Option 2.
Step-by-step explanation:
The antifreeze claims to protect between -30 C and 130 C. The inequality should be this: 
You can replace C with the Fahrenheit formula: C=
So, the inequality becomes
