Answer:

  185°

Step-by-step explanation:

The triangle internal angle at Y is 145° -45° = 100°. Since the triangle is isosceles, the internal angles at X and Z are both (180° -100°)/2 = 40°. Then the bearing of Z from X is the bearing of Y from X less the internal angle at X:

  (45° +180°) -40° = 185°.

Z from X is 185°.

Answer:

s=13

Step-by-step explanation:

As\ we\ know\ that,\\"The \ sum\ of\ all\ angles\ of\ a\ triangle\ is\ 180"\\Hence,\\(4s+9)+(3s+1)+(6s+1)=180\\4s+3s+6s+9+1+1=180\\13s+11=180\\13s=180-11\\13s=169\\s=13

PLEASE HELP ASAP!!!!!
Rashid [163]

mike charges 100 dollars service charge plus 65 dollars per hour.  

amy charges 40 dollars service charge plus 80 dollars per hour.  

the cost to repair from mike is 100 + 65 * x.  

the cost to repair from amy is 40 + 80 * x.  

let x = 3 and you get:  

the cost to repair from mike is 100 + 65 * 3 = 295 dollars.  

the cost to repaid from amy is 40 + 80 * 3 = 280 dollars.  

as long as the time to repair is 3 hours or less, the cost to repair will be cheaper from amy.

What is (30 1/9 + 4 1/3) - 19 5/6
weqwewe [10]
14 11/18
I got this answer by doing 30 1/9 + 4 1/3= 34 4/9
Now I subtracted 34 4/9 by 19 5/6 to get the answer 14 11/18
TIP: When adding/subtracting/multiplying/dividing mixed numbers change them to an improper fraction first by multiplying the denominator and the whole number then adding the numerator

The volume of a cylinder is 980pi in ^3 The height of the cylinder is 20 in. What is the radius of the cylinder?
siniylev [52]

Answer:

The radius of the cylinder is 7 in

Step-by-step explanation:

To calculate the radius of a cylinder we have to use the following formula:

v = volume  = 980π in³

h = height = 20in

π = pi

r = radius

v = (π * r²) * h

we replace with the known values

980π in³  = (π * (r)²) * 20in

980π in³ / 20in = π * (r)²

49 in² = (r)²

√(49 in²) = r

7 in = r

The radius of the cylinder is 7 in
