Answer:

Los lados correspondientes de un polígono son los lados que están en la misma posición en polígonos similares. En geometría, encontrar la congruencia y la similitud implica comparar los lados correspondientes y los ángulos correspondientes de los polígonos. En este artículo, aprendamos más sobre triángulos rectángulos similares, lados correspondientes, su definición, cómo son proporcionales

Two triangles: left triangle with y degrees and 40 degrees and right triangle with x degrees.

40 degrees from the left triangle, when adding with the unknown angle of the right triangle, is equal to 180 degrees.
Adding left triangle's (third) undetermined angle and x degrees angle (the other same angle), is equal to 90 degrees.
The right triangle is an isosceles triangle, meaning two equal angles, and one of them is x degrees. Thus, the other same angle is also x degrees.

----------------------------------------------------------------------------------------------------------

1) Subtract 180 - 40 = 140 degrees. 140 degrees is the unknown angle of right triangle.

2) 140 + x + x = 180 (equation)

140 + 2x = 180
2x = 180 - 140
2x = 40
x degrees = 20 degrees

ANSWER: x = 20 DEGREES

----------------------------------------------------------------------------------------------------------

1) With knowledge of x degrees being 20 degrees, the other same angle is 20 degrees, too.

2) Subtract 90 - 20 = 70 degrees. 70 degrees is the (third) undetermined angle

of left triangle.

2) 70 + 40 + y = 180

110 + y = 180
y = 180 - 110
y = 70 degrees

ANSWER: y = 70 DEGREES

Alicia is making cupcakes for a party she is having and wants to make sure everyone gets at least one cupcake. The recipe calls

Liula [17]

$\frac{84}{21}=4$

Therefore you need 4 batches of cupcakes if you want every person to get one cupcake.

This means you multiply the amount of salt per batch by the number of batches, to get the total amount of salt you need.
Each batch contains 1 teaspoon of salt for 21 cupcakes. Multiply: $4\text{ batches of cupcakes}\times1\text{ teaspoon of salt}=4\text{ teaspoons salt}$ for the whole thing.

A man is in a boat 2 miles from the nearest point on the coast. He is to go to point Q, located 3 miles down the coast and 1 mil

mafiozo [28]

Answer:

The answer is "0.45385".

Step-by-step explanation:

The time is taken to reach the coast $= \frac{\sqrt{(2^2 + x^2)}}{4}$

The time is taken to reach Q after reaching the coast $= \frac{\sqrt{(1 + (3-x)^2)}}{4}$

Total time, $T= \frac{\sqrt{(1 + (3-x)^2)}}{4}+ \frac{\sqrt{(1 + (3-x)^2)}}{4}$

This has to be minimum,

$\to \frac{dt}{dx} = 0$

$\to \frac{\sqrt{(2^2 + x^2)}}{2} + \frac{\sqrt{1 + (3-x)^2}}{3}\\\\ \frac{x}{4}\sqrt{(4+x^2)} + \frac{(x-3)}{(4\sqrt{(x^2-6x+10)}} = 0\\\\\frac{x^2}{16} \times (4+x^2) = \frac{(x-3)^2}{16 \times (x^2-6x+10)}\\\\x^2(4+x^2) = \frac{(x-3)^2}{(x^2-6x+10)}\\\\4x^2+x^4 = \frac{ x^2+9-6x}{(x^2-6x+10)}\\\\ 4x^2+x^4(x^2-6x+10) = x^2+9-6x\\\\4x^4-24x^3+40x^2+x^6-6x^5+10x^4= x^2+9-6x\\\\x^6-6x^5+ 14x^4-24x^3+39x^2+6x-9=0\\\\$

x=0.45385
