Since the square is folded along its diagonal,

Perimeter of each triangle

= 2 * Side of square + Diagonal of square.

Side of square

= √(Area of square)

= √(49in²) = 7in.

Diagonal of square

= √(2 * Area of square)

= √(98in²) = 7√2in.

Hence we have 2 * 7in + 7√2in = 7(2 + √2) in.

When Jose woke up the temperature was 74°. It

reached a high temperature of 91°. What was

the percent of increase of these temperatures?

Answers

Answer:

22.97

Step-by-step explanation:

Given that,

Initial temperature = 74°

After some time, the new temperature = 91°

We need to find the percent increase in the temperature.

The formula for the percentage increase is given by :

[tex]\%=\dfrac{|\text{final value-initial value}|}{\text{initial value}}\times 100\\\\=\dfrac{91-74}{74}\times100\\\\=22.97\%[/tex]

So, the increase in temperature is 22.97%.

A figure has been dilated from the origin by a scale factor of one seventh. if another dilation from the origin maps the dilated image back
onto the original figure, what is its scale factor?

Answers

Answer:

its scale factor is 3

Step-by-step explanation:

plz mark brainliest

To map the dilated image back  onto the original figure, the scale factor needed is 7.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the increase or decrease in the size of a figure by a factor.

If a figure is dilated from the origin by a scale factor of one seventh, it is given by:

(x, y) ⇒ [(1/7)x, (1/7)y]

To map the dilated image back  onto the original figure, the scale factor needed is 7. Hence:

[(1/7)x, (1/7)y] ⇒ (x, y)

2.) Find the unknown side length. Simplify answers that are radicals.
16
12

Answers

Answer:

1.) 5              2.) 10.58

Step-by-step explanation:

For each one, you use the equation a^2 + b^2 = c^2 where c is the "hypotenuse"-- the side of the triangle opposite (facing) the right angle which is shown with a small box. The variables a and b do not matter, as long as they are the "legs", the other 2 sides.

So it is 4^2 + 3^2 = c^2 which simplifies to 16+9=25=c^2 and square root both sides and you get c=5

and 12^2 + b^2 = 16^2 which simplifies to 144+ b^2 = 256 and subtract 144 from both sides and you get b^2 = 112 and square root both sides and it is approximately 10.6 :)

If triangle A B C is congruent to triangle D E F, the measure of angle A equals 55 degrees, and the measure of angle E equals 25 degrees, what is the measure of angle C?
A. 25°
B. 55°
C. 80°
D. 100°

Answers

Answer:

D. 100

Step-by-step explanation:

Answer:

100°

Step-by-step explanation:

Since ΔABC ≅ Δ DEF, and the sum of the measures of the interior angles of a triangle is 180°, subtract the given angle measurements from 180°.

∠A ≅ ∠D, ∠B ≅ ∠E, ∠C ≅ ∠F (The vertices are written in this order because they are corresponding angles.)

180° - 55° = 125° - 25° = 100°

∠C is 100°
