Which expressions correctly represent the area of the triangle XYZ?

Mathematics
1 answer:
Evgen [1.6K]3 years ago
6 0

Answer:

Options (2) and Option (1)

Step-by-step explanation:

Area of the ΔXYZ = \frac{1}{2}(\text{Base})(\text{Height})

                              = \frac{1}{2}(XZ)h

                              = \frac{1}{2}(18)h

By applying sine rule in the ΔYPZ,

sin(38°) = \frac{\text{Opposite side}}{\text{Hypotenuse}}

sin(38°) = \frac{h}{14}

h = 14[sin(38°)]

Therefore, area of the given triangle = \frac{1}{2}(18)(14)sin(38)

By applying sine rule in ΔYPZ,

sin(58°) = \frac{\text{Opposite side}}{\text{Hypotenuse}}

sin(58°) = \frac{h}{10}

h = 10sin(58°)

Area of ΔXYZ = \frac{1}{2}(18)(10)sin(58)

Therefore, Options (2) and Option (1) are the correct options.

David can paint a fence in ten hours. Alex can paint the same fence in eight hours. If
xxTIMURxx [149]

Answer:

40/9

Step-by-step explanation:

Use the work formula, \frac{1}{A} + \frac{1}{B} = \frac{1}{T}, where A is the amount of time it takes one person, B is the amount of time it takes another person, and T is the time it takes for them to work together.

Plug in the times for David and Alex alone:

\frac{1}{10} + \frac{1}{8} = \frac{1}{T}

Find the least common denominator, which is 40.

\frac{4}{40} + \frac{5}{40} = \frac{1}{T}

\frac{9}{40} = \frac{1}{T}

Cross multiply and solve for T:

9T = 40

T = 40/9

So, if they worked together, it would take them 40/9 hours
