Trigonometric ratios in rig triangles pls help

c 21 / 29

Step-by-step explanation:

with reference angle α

base (b) = 21

hypotenuse (h) = 29

Now

cos α = b/h

= 21/ 29

Hope it will help you :)

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
