Answer:

19.1

Step-by-step explanation:

27 is half of 54, so that means that the second triangle is 1/2 the size of the first, meaning all sides need to be divided by 2 in order to get the answers for each side

Give the equation of the line that is parallel to y=-3x+1 and goes through (-5,-6)
stich3 [128]

Hi there! The answer is y = -3x - 21

Let's set up the equation of the line step by step! First we need to know that we need to set up an equation in slope-intercept form. We get the following:

y = ax + b.
a represents the slope of the line.
b represents the intercept with the y-axis.

Since our new line is parallel to y = -3x + 1, both lines have the same slope. Therefore the slope of our line, which is represented by a, is -3.

y = -3x + b.
We also know that this line goes through the point (-5, -6) and therefore we can plug in these coordinates into our formula.

-6 = -3 × -5 + b
Simplify

-6 = 15 + b
Subtract 15

-21 = b
Switch sides

b = -21
Hence, y = -3x - 21

~ Hope this helps you!

What are the ratios for sin A and cos A? The diagram is not drawn to scale.
trapecia [35]

Answer:

C

Step-by-step explanation:

Sin represents opposite/hypotenuse. Thus, when A is the reference angle, 21 is the measure of the opposite side (CB) and 29 is the measure of the hypotenuse (AB).

Cos represents adjacent/hypotenuse. Therefore, when A is the reference angle, 20 is the measure of the adjacent side (AC) and 29 is the measure of the hypotenuse (AB).

The length of a pair of corresponding sides of two similar ∆'s are 3 cm and 11 cm. If the area of the first ∆ is 18 cm^2 find th
AnnZ [28]

Answer:

The area of the second triangle is 242 cm²

Step-by-step explanation:

In the similar triangles

  • The ratio between their perimeters equals the ratio between their corresponding sides
  • The ratio between their areas equals square the ratio between their corresponding sides

∵ The length of a pair of corresponding sides of two similar ∆'s are

   3 cm and 11 cm

→ Find the ratio of the corresponding sides

∴ The ratio of their corresponding sides = \frac{3}{11}

∵ The area of the first ∆ is 18 cm²

→ Use the second rule above

∵ \frac{A1}{A2} = (\frac{3}{11}) ^{2}

∵ A1 = 18 cm²

→ Substitute it in the ratio above

∴ \frac{18}{A2} = \frac{9}{121}

→ By using the cross multiplication

∵ A2 × 9 = 18 × 121

∴ 9A2 = 2178

→ Divide both sides by 9

∴ A2 = 242 cm²

∴ The area of the second triangle is 242 cm²
