Tomtit [17]4 years ago

Answer:

SAS Similarity Theorem

Step-by-step explanation:

we know that

<u>SAS Similarity Theorem</u>: States that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar

In this problem

∠HJZ=∠RJW ----> by vertical angles

and

WJ/HJ=JR/JZ

substitute the values

8/4=6/3

2=2 ----> is true

so

Two sides of triangle HJZ are proportional with the two corresponding sides of triangle WJR and the included angle is congruent

therefore

Triangles are similar by SAS Similarity Theorem

If I have the letter x after a number, what does it mean?<br><br> Ex. 20x = 5
Rzqust [24]

Answer:

It means that 20 times x is 5

also the answer to that problem (20x=5) is 1/4

Step-by-step explanation:

20x means

20 * x

and since 20 * x = 5

divide 5 and 20

5/20 = 1/4

Find the measure of angleq, the smallest angle in a triangle whose sides have lengths 4, 5, and 6. round the measure to the near
Pavlova-9 [17]

The measure of the ∠Q = 41°

By law of cosines:

a law in trigonometry: the square of a side of a plane triangle equals the sum of the squares of the remaining sides minus twice the product of those sides and the cosine of the angle between them.

Which can we stated as:

{q}^2 = {p}^2 + {r}^2 - 2prcos(Q)\\{4}^2 = {6}^2 + {5}^2 - 2*6*5*cos(Q)\\\\

solving equation using normal algebra:

60cos(Q) = 36 + 25 - 16

60 cos(Q) = 45

cos(Q) = 45/60

cos(Q) = 3/4

Q = {cos}^{-1} (\frac{3}{4})\\

Thus, Q = 41°

Hence, the measure of the smallest angle in a triangle whose sides have lengths 4, 5, and 6. ∠Q is 41°.

Ella purchased a game that was on sale for 12% off. The sales tax in her county is 6%. Let y represent the original price of the
Vera_Pavlovna [14]

y:  original price (in dollars)

0.12y:  amount of discount (in dollars)

sale price:  y - 0.12y = 0.88y

sales tax on this sale price:  (0.06)(0.88y)

final cost:  0.88y + (0.06)(0.88y) = 0.88y(1+0.06) =  0.9328y
