Step-by-step explanation:
Hope this helps!
5^(-4) / 5^3 = 5^(-4 - 3) = 5^(-7)
30 2 1
--- = 7 -- = 7 --
4 4 2
Now this is how it should look like. You will divide 30/4 = 7.5 or 7 and 2/4
Answer:
x = 2
Step-by-step explanation:
3 3/8+4 5/7x=12 45/56
Solve :
3 3/8+4 5/7x=12 45/56
27/8 + 33/7 x = 717/56
33/7 x = (717 - 189) / 56
33/7 x = 528/56
x = 2
We know that
the law of sines established
a/sin A=b/sin B--------sin A=[a*sin B]/b
a=4.5 cm
b=6 cm
B=35°
so
sin A=[4.5*sin 35°]/6-----> sin A=0.43018
A=arc sin(0.43018)-------> A=25.5°
the answer is the option
<span>C) 25.5° </span>
