Write the ratios for sin A and cos A. The triangle is not drawn to scale

Mathematics
1 answer:
Bumek [7]3 years ago
5 0

Answer:

sin(A)=\frac{48}{50}, cos(A)=\frac{14}{50}

Step-by-step explanation:

Part a) Find the sin(A)

we know that

In the right triangle ABC

sin(A)=\frac{BC}{AB} ----> the sine of angle (A)  is the opposite side angle (A) divided by the hypotenuse

substitute the values

sin(A)=\frac{48}{50}

Part b) Find the cos(A)

we know that

In the right triangle ABC

cos(A)=\frac{AC}{AB} ----> the cosine of angle (A)  is the adjacent side angle (A) divided by the hypotenuse

substitute the values

cos(A)=\frac{14}{50}

Point A lies on the circle and has an x-coordinate of –3. Which value could be the y-coordinate for point A? 2.5 2.8
vodka [1.7K]

Answer:

the other point could be 2.8

Step-by-step explanation:

in circle values of both x and are almost equal in magnitude

since 2.8 is closest to 3 i magnitude

hence 2.8 will  be correct option

this point will lie in third coordinate

as  third coordinate has points

(-x,y)

and coordinates of points lie on the circle are

(-3,2.8)

Answer:

<h3>           A.   A = 66π cm² ≈ 207.35 cm²</h3><h3>           B.  No, will not. {will be less than double}</h3><h3>           C.  No, will not. {will be more than double}</h3>

Step-by-step explanation:

<h3>A.</h3>

h = 8 cm,  r = 3 cm

A = 2×πr² + 2πr×h = 2πr×(r + h)

A = 2π×3×(3 + 8) =  66π cm² ≈ 207.35 cm²

<h3>B.</h3>

h = 2×8 = 16 cm ,      r = 3 cm ,   2×66π = 132π cm²

A = 2π×3×(3 + 16) =  114π cm² ≠ 132π cm²  

<h3>C.</h3>

h = 8 cm ,        r = 2×3 = 6 cm  ,   2×66π = 132π cm²

A = 2π×6×(6 + 8) =  168π cm² ≠ 132π cm²

Can someone help me with my last question
slega [8]
What you need to do is that you plug p=3 into the expression [(5.4p+5)+(8+3.2p)]/2 and you have:
[(5.4*3+5)+(8+3.2*3)]/2
= (21.2+ 17.6)/2
= 38.8/2
= 19.4

The average of the two boys' points is p=3 is 19.4 points~
