Because thee dimensions of ΔRAH is twice as large as corresponding dimensions of ΔEAC,

|RA|=2|EA|=2*3.5=7

|AH|=2|AC|=2*6=12

So, we have that 2 corresponding sides are in proportion and angle between them =90⁰, so the angle between them are congruent,

we can use SAS to prove that these triangles are similar.

What is the surface area of the square pyramid represented by the net below?

4vir4ik [10]

Answer:

64 cm^2

Step-by-step explanation:

Square: 4*4 = 16

Triangles: 4((4*6)/2))

= 4(24/2)

= 4(12)

= 48

Add the square and triangles together

= 16 + 48

= 64

The total will be 64 cm^2

Segment addition with variables

oksian1 [2.3K]

<em>x equals 22</em>

<h2>Explanation:</h2>

____________________________________________

The Segment Postulate states the following:

<em>Given two end points A and B, a third point C lines on the segment AB if and only if the distances between the points satisfy the equation:</em>

$\overline{AB}=\overline{AC}+\overline{CB}$

____________________________________________

From the figure:

$\overline{AC}=8+x \\ \\ \overline{CB}=10 \\ \\ \overline{AB}=40$

Our goal is to find x:

$\overline{AB}=\overline{AC}+\overline{CB} \\ \\ Substituting \ values: \\ \\ 40=(8+x)+10 \\ \\ 18+x=40 \\ \\ Subtracting \ 18 \ from \ both \ sides: \\ \\ 18-18+x=40-18 \\ \\ \boxed{x=22}$

Use any method to solve the equation. If necessary, round to the nearest hundredth.7x2 − 16x = 8

Semmy [17]

7x^2 - 16x - 8 = 0

using the quadratic formula x = [ -(-16)+/- sqrt((-16^2 - 4*7-8] / 2*7

= (16 +/1 sqrt 480) / 14

= 2.71, -0.42 to nearest hundredth

The logo for a new company is a circle divided into 24 equally sized sectors. Six of the sectors are white, and the others are d

AveGali [126]

Answer:

r = 2.5

Step-by-step explanation:

the area of the whole circle = $\frac{13}{50}$ *π * 24

A = πr² = (13π*24)/50

r = √((13*24)/50) = 2.5 inches
