Solve for the missing length and the other two angles in the triangle below
Klio2033 [76]

Answer:

AC = 3.72 units

Angles:

A = 132.6°

C = 27.4°

Step-by-step explanation:

AC² = 5² + 8² - 2(5)(8)cos(20)

AC² = 13.82459034

AC = 3.718143399

3.718143399/sin20 = 8/sinA

sinA = 0.7358944647

A = 180 - 47.38285134

A = 132.6171487

3.718143399/sin20 = 5/sinC

sinC = 0.4599340405

C = 27.38285134

Julie has a large red apple in her hand that is 4 ft off the ground. A blue bird sees the apple at an
Dafna1 [17]

Answer:

Step-by-step explanation:

so from the silly drawing,  you can see that the triangle is 4 feet off the ground, and that we want to find the Opp side from our angle of 15 °

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

use TOA to find the Opp side of the triangle .. which is labeled X

Tan(15) = X / 15

15* Tan(15) = X

4.019   =   X

so the bird is up 4 feet in the tree.. not very high up, plus the 4 feet that the apple is already off the ground, soo

the tree... to where the bird is, at least, is 8.019 feet..

did this make sense?  :/  

hope the drawing helped  :P

Please help! Identify the minimum value of the function y=3x^2-12x+10.
Dimas [21]
The lowest point is at the vertex, or U-turn.

\bf \textit{ vertex of a vertical parabola, using coefficients}\\\\
\begin{array}{llccclll}
y = &{{ 3}}x^2&{{ -12}}x&{{ +10}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad  {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)
\\\\\\
\left( -\cfrac{-12}{2(3)}~~,~~10-\cfrac{(-12)^2}{4(3)} \right)\qquad \textit{so the lowest value is at }10-\cfrac{(-12)^2}{4(3)}

PLSSS HELPPP!!! I dont get it
Licemer1 [7]

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

Point D is about 1/4 of the way from C to A on segment AC.

Point D' will be about 1/4 of the way from C' to A' on segment A'C'.

If you have a compass, dividers, or ruler, you can copy the distance DC to D'C' to place the point more or less exactly.
