Step-by-step explanation:

53°+44°+46°+x=360°(complete circle)

or,143°+x=360°

or,x=360°-143°

or,x=217°

hope this helps you.

Answer:

X= 143°

Step-by-step explanation:

You could do it your way or as you can see, there's a right angle, which equals 90°, so you could either add 44+46+53 or 90+53. You get the same answer, which is 143°.

The area of a trampoline is 49 pi sqared. What's the diameter of the trampoline?

Flauer [41]

Answer:

The diameter is 14

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know the area is 49 pi

49 pi = pi r^2

Divide each side by pi

49 pi/ pi = pi r^2/pi

49 = r^2

Take the square root of each side

sqrt(49) = sqrt(r^2)

7 =r

We want the diameter

d = 2r

d = 2*7

d = 14

If y = kx, what is the value of x if y = 0.33 and k = 1/4?

ololo11 [35]

Easy

plug them in
0.33=1/4(x)
times both sides by 4/1 (4/1 times 1/4=4/4=1)
0.33*4/1=4/4x
1.32=1x
1.32=x
x=1.32

4% of $2659
= 0.04 x 3659
= $146.36

----------------------------------------
Total contribution to his 401k
