Answer:
d) √2/2
Step-by-step explanation:
cos∠E= 5/5√2= 1/√2=√2/2
Correct option is d)√2/2
Answer:
The expression a^b
means that we multiplicate the number a by itself b times.
So x^2 means that we multiplicate the number x by itself 2 times:
x^2 = x*x
and 2^x means that we multiplicate the number 2 by itself x times
2^x = 2*2*2*....*2 (if you count them, you should see x times the number 2)
for example, if x = 4, we will have
2^4 = 2*2*2*2
Answer:
a=18.1 or √329
Step-by-step explanation:
a²+b²=c²
a²+20²=27²
a²+400=729
a²=329
a=18.1 or √329 depending on what form you are answering in, radical or decimal.
