The triangles above are similar write a similarity statement if possible solve for x the images are not drawn to scale

e-lub [12.9K]

Answer:

The value of x is 8.

Step-by-step explanation:

In triangle PQR and XZY,

$\angle P=\angle X=90^{\circ}$

$\angle Q=\angle Z$

$\angle R=\angle Y$

By AA property of similarity, we can say that

$\triangle PQR\sim \triangle XZY$

The similarity statement is $\triangle PQR\sim \triangle XZY$ .

The corresponding sides of similar triangles are proportional. Since both triangles are similar, so

$\frac{PQ}{QR}=\frac{XZ}{ZY}$

$\frac{21}{28}=\frac{5x+2}{7x}$

$\frac{3}{4}=\frac{5x+2}{7x}$

$7x\times 3=(5x+2)\times 4$

$21x=20x+8$

$21x-20x=8$

$x=8$

Therefore the value of x is 8.

Tamara earns her living as a salary plus commission employee. Her annual salary is $48,000, and she earns 4% commission on all s

aleksklad [387]

Answer: b is the correct option

Step-by-step explanation:

Tamara earns her living as a salary plus commission employee. This means that the total amount she earns is not fixed.

Her annual salary is $48,000. There are 12 months in a year. This means

that her her monthly salary is 48000/12 = $4000

she earns 4% commission on all sales she makes.

If Tamara wants to make a total of $6,000 this month, it means that she wants to make an extra $2000($6000-$4000) this month. She can only make this from commission based on sales

Let the sales be x

4% of x = 2000

4/100 × x = 2000

0.04x = 2000

x= 2000/0.04 = $50000

Question 11

dem82 [27]

Answer:

There were 49 questions on this Geometry test.

Step-by-step explanation:

You can start by setting up a proportion:

x = total number of questions on Geometry test

$\frac{37}{x}$ = $\frac{75.51}{100}$

Now, to solve for x, cross multiply:

75.51x = 3700

Finally, isolate x and solve:

x = 49.0001324328

This is very close to 49.
