Find the height and area of each of these triangles ​
andreev551 [17]

Answer:

area= 1/2*(h*b) h- height, b- base

the triangle is isosceles (denoted by the 2 dashes on the sides of the triangle)

so they are equal in length

angles in triangle = 180

so 38+38=76

180-76=104

base=24

divide the triangle in the center

so now triangle 1(left) the base = 12

and triangle 2(right) the base = 12

use trigonometric ratios

in this we need to find the height

which is opposite of 38,

we already have the adjacent =12

so the ratio is Tan (Tangent Opposite/Adjacent)(TOA)

Tan38= (12/h)

multiply by h

h*Tan38=12

h=12/tan38 = 15.35929959

What property was used on 14k + 2 (3k+5) -5 = 10 to obtain 14k + 6k +10 - 5 =10
Elis [28]

\boxed{\text{The distributive property}}\\\\\text{In order to solve the equation, you would have to first use the }\\\text{distributive property:}\\\\14k + 2 (3k+5) -5 = 10\\\\\text{Distribute the 2 to the variables inside the parenthesis}\\\\14k+6k+10-5=10\\\\\text{You can see that your outcome matches the equation in the question}\\\\\text{Therefore, the distributive property would be your answer}

Which of the following is an extraneous solution of startroot 4 x 41 endroot = x 5? x = –8 x = –2 x = 2 x = 8
Gnom [1K]

The extraneous solution of startroot 4 x 41 endroot = x 5 will be A. -8.

<h3>What is an extraneous solution?</h3>

It should be noted that an extraneous solution simply means a root of a transformed equation which isn't part of the original equation.

✓4x + 41 = x + 5

Square both sides

4x + 41 = x² + 10x + 25

x² + 6x - 16

x(x + 8) - 2(x + 8) = 0

x + 8 = 0

x= 0 + 8 = 8

Delia, Edwin and Freya share some money in the ratio 5:7:8 Freya's share is £1600 how much did they share?
andrey2020 [161]

Answer: £ 400,560,640

Step-by-step explanation:

Given

Delia, Edwin, and Freya share £1600 in the ratio 5:7:8

Suppose, their shares are 5x,7x, and 8x such that the ratio remains the same.

The sum of their shares must be £1600

\Rightarrow 5x+7x+8x=1600\\\Rightarrow 20x=1600\\\\\Rightarrow x=\dfrac{1600}{20}\\\\\Rightarrow x=80

Their share is

Delia:5\times 80=400

Edwin:7\times 80=560

Freya:8\times 80=640
