Answer:

Step-by-step explanation:

A) In ΔONE & ΔEST

ON // ST (Construction) and NS is transversal.

∠1 = ∠4 {alternate interior angles}

NE =ES {Given E is midpoint}

∠2 = ∠3 {Vertically opposite angle}

ΔONE ≅ ΔEST { A S A congruent}

OE ≅ TE {CPCT}

ON = ST {CPCT} ---------(I)

ON = OH -----------------(II)

From (I) & (II)

OH = ST & OH // ST (construction)

OHST is a parallelogram.

So, OE // HS -----------------(A)

OE = TE

OT = 2OE

OE = (1/2)OT

OE = (1/2)HS ------------------(B)

From A & B , midpoint theorem is proved

The length of FD = 0.76 feet.

Step-by-step explanation:

Given that in ΔDEF, the angle F measures 90° and the angle D measures 83° and EF=6.2 feet

To find the length of FD, let us use the tangent function. The tangent of an angle is the length of opposite side divided by the length of the adjacent side.

$\tan \theta=\frac{o p p}{a d j}$

From the given data, θ=83°, $o p p=6.2$ and $a d j=x$

Substituting these values in the tangent formula, we get,

$\begin{array}{r}{\tan \theta=\frac{o p p}{a d j}} \\{\tan 83^{\circ}=\frac{6.2}{x}}\end{array}$

Using calculator, the value of $\tan 83^{\circ}=8.14$ and substituting and solving the equation, we get,

$\begin{aligned}8.14 &=\frac{6.2}{x} \\x &=\frac{6.2}{8.14} \\x &=0.76\end{aligned}$

Thus, the length of FD = 0.76 feet.

Domain of function y=|x|

Naddik [55]

Answer:

All real number

Step-by-step explanation:

The graph of y = x is shown to the right. We can see that it is defined for all x-values because the line will continue to infinity. Thus, the domain of y = x is all real numbers.

[6] Jessica sold one third of her records and then bought 84 more. She now has 178 records. How many records did Jessica begin w

tia_tia [17]

Answer:

141 records

Step-by-step explanation:

Let the initial number be x

x - 1/3x = 2/3x

<u>Bought 84 more and now got 178:</u>

2/3x + 84 = 178
2/3x = 94
x = 94 ÷ 2/3
x = 94 × 3/2
x = 141

Jessica had 141 records initially
