Answer:
sin A = 4/5
cos A = 3/5
Step-by-step explanation:
SOHCAHTOA
cot A = 1/tan A
tan A = opp/adj
cot A = 1/tan A = adj/opp
cot A = 3/4
adj = 3; opp = 4
adj^2 + opp^2 = hyp^2
3^2 + 4^2 = hyp^2
9 + 16 = hyp^2
hyp = 5
sin A = opp/hyp
sin A = 4/5
cos A = adj/hyp
cos A = 3/5
Answer:
sin A = 4/5
cos A = 3/5
Answer:
the 8th exterior angle is 49 degrees
Step-by-step explanation:
The sum of the exterior angles of an octagon is 360 degrees
(this is true for all polygons)
42°+55°+ 39°+ 20°+ 62°+45°,+ 47+x = 360
combine like terms
311+x=360
subtract 311 from each side
311-311 +x = 360-311
x=49
Answer:
When we divide powers of the same base, this means that we have to do is subtract the exponents. ... In other words, all we would need is to divide two powers that have the same exponent then the subtraction would lead to zero
Answer:
x=3
y=2
Step-by-step explanation:
The comments are that they both are multidigits numbers
