Solve for x using figure to the right. Pls answer this it is urgent
goldenfox [79]

Answer:

Therefore the value of x = 10 units

Step-by-step explanation:

Let label the Triangles first,

Δ ABC a right triangle at ∠ A =90°

Δ ADB andΔ ADC a right triangle at ∠ D =90°

Such that

AD = x

BD = 50

CD = 2

∴ BC = BD + DC = 50 + 2 = 52

To Find:

x = ?

Solution:

In right triangle  By Pythagoras Theorem,

(\textrm{Hypotenuse})^{2} = (\textrm{Shorter leg})^{2}+(\textrm{Longer leg})^{2}

In right triangle Δ ADB andΔ ADC  By Pythagoras Theorem we will have,

AB² =  BD² + AD²

AB² = 50² + x²            ..................equation ( 1 )

and

AC² = DC² + AD²

AC² = 2² + x²             ...................equation ( 2 )

Now in right triangle Δ ABC,

BC² = AB² + AC²

Equating equation  (1 ) and ( 2 ) and the given value we get

52² = 50² + x² + 2² + x²

∴ 2x² = 2704 - 2504

∴ 2x² =200

∴ x^{2} =\frac{200}{2}\\\\\therefore x=\pm\sqrt{100} \\\\ \textrm{x cannot be negative}\\\therefore x= 10\ unit

Therefore the value of x = 10 units

Find the measure of the arc or angle indicated.
Shkiper50 [21]

Answer:

15) ∠BCD = 1/2 short arc BC = (360° -260°)/2 = 50° (C)

16) ∠K is supplementary to short arc JL = 180° -120° = 60° (C)

17) ∠V is half the difference of long arc TW and short arc UW.

.. (198° - UW)/2 = 69°

.. 198° -138° = UW = 60° (C)

18) ∠L is supplementary to short arc KM

.. KM = 180° -66° = 114° (C)

Step-by-step explanation: hope it helped
