False because a number is rational if we can write it as a fraction where the top number of and bottom number are both whole numbers but irrational numbers is any number that is not rational. It is a number that cannot be written as a ratio of two integers(or cannot be expressed as a fraction)
Answer:
83.9°
Step-by-step explanation:
Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
a= 13 cm
a2= 169cm
b= 4cm
b2=16 cm
a2+b2= 185cm (c2)
c=13.6cm
after wards use the law of cosines and c= 83.9°
Answer:
cos A = x.
Step-by-step explanation:
Because we have a right-angled triangle, m < A + m < C = 90 and sin C = Cos A.
So cos A = x.
Answer:
-1.6
Step-by-step explanation:
m=y2-y1/x2-x1
(-4)-4=(-8)
4-(-1)=5
-8/5=(-1.6)
hope this helps :3
if it did pls mark brainliest
