Step-by-step explanation:
sin 45°=opp/hyp
1/root 2= 4/z
z=4 root 2
A= 45 and b=45
It is an isosceles triangle therefore has both two equal sides and two equal angles.
Answer:
its -1.66666666667
Step-by-step explanation:
you are thinking of 5x-3, remember you have the number 5 dividedinto -3 parts
Answer: 5
Step-by-step explanation:
a^2 + b^2 = c^2
12^2 + x^2 = 13^2
144 + x^2 = 169
x^2 = 25
square root both sides
x = 5
to check, do 12^2 + 5^2 =169
sqrt of 169 is 13
