➷ Angle XBC = 55 degrees because corresponding angles are equal

b) We already know angle XBC

Angle XCB = Angle XBC because isosceles base angles are equal

Therefore, angle XCB = 55 degrees

Angles in a triangle equal 180 degrees

180 - (55 + 55) = 70

Angle BXC = 70 degrees

8x + 5y = 22<br> -8x + y = 14
finlep [7]

Answer:

Y = 6 X=-1

Step-by-step explanation:

  1. Add the numbers 8x+-8x=0. 5y+y=6y. 22+14=36
  2. So that means 6y=36. So Y would equal 6
  3. Substitute the values it one of the original equations. 8x + 5(6) =22. 8x+30=22
  4. Minus 22 from both sides.
  5. That would give you 8x=-8
  6. So x would equal - 1

What is the rate of change of the water level , in feet per hour
miskamm [114]
A; rate of change is the same as slope, so, using the slope formula, m= \frac{y_{2} - y\1_{1}   }{ x_{2} - x_{1} }, where m is the slope and x_{1}, x_{2}, y_{1}, and y_{2} are the x and y values.

Plug in 2 points for x and y, water level being the y and time being the x since we're looking for the answer in ft/hr-- you can choose any two, but from the same row.

m= \frac{ 30-50}{4-0}
m= \frac{-20}{4}
m= \frac{-5}{1}
m= -5 ft/hr
