VWX and NOP are similar. If mV = 44° and mP = 66°, what is<br> mW?

Sladkaya [172]

Answer: 70°

<u>Step-by-step explanation:</u>

ΔVWX ≅ ΔNOP ⇒ ∠V=∠N, ∠W=∠O, and ∠X=∠P

Since ∠V=44° and ∠P=66°=∠X

then we can use the Triangle Sum Theorem:

∠V + ∠W + ∠X = 180°

44° + ∠W + 66° = 180°

∠W + 110° = 180°

∠W = 70°

Michael's bill at a restaurant was $46.32. He wants to leave a 17% tip. What will the new total be,including the tip?

Novosadov [1.4K]

$7.87+$46.32=$54.19. If you multiply 46.32 by 0.17, 17%, it is 7.87 so you just add that to the original bill, 46.32

Find the equation of a line tangent to the circle (x−1)^2+y^2=26 at the point (2, −5).

77julia77 [94]

Center of circle is ( 1, 0).

Slope of normal passing though ( 1, 0 ) and ( 2, -5 ) is :

$m_p=\dfrac{0-(-5)}{1-2}\\\\m_p=-5$

So, slope of tangent will be :

$m_t=-\dfrac{1}{m_n}\\\\m_t=\dfrac{1}{5}$

Equation of tangent :

$y-(-5)=\dfrac{1}{5}(x-2)\\\\5y+25=x-2\\\\5y-x+27=0$

Hence, this is the required solution.
