Are the polygons below similar? If they are, write a statement and give the scale factor.

olchik [2.2K]

Answer:

Yes they are similar. Triangle ABC is similar to Triangle FED. The scale factor from large to small is 3/4 or small to large is 4/3.

Step-by-step explanation:

To determine if two triangles are similar, their corresponding sides create equal ratios.

$\frac{AB}{FE} = \frac{BC}{ED}= \frac{CA}{FD} \\\\\frac{15}{20} =\frac{12}{16} =\frac{18}{24} \\\\ \frac{3}{4} =\frac{3}{4} =\frac{3}{4}$

This ratio is the scale factor depending on which is the pre-image. 3/4 or 4/3.

Solve the equation for [0,2pi]<br> cos2x=1/sqrt2

lapo4ka [179]

$cos(2x) = \frac{1}{\sqrt{2}}$
$cos(2x) = \frac{1}{\sqrt{2}} * \frac{\sqrt{2}}{\sqrt{2}}$
$cos(2x) = \frac{\sqrt{2}}{2}$
$cos(2x) = cos(45)$
$cos(x) = cos(22.5)$
$x = 22.5$

in triangle ABC the measure of angle B is 24° more than three times the measure of angle a the measure of angle C is 51° more th

ValentinkaMS [17]

M∠A = x
m∠B = 3x+24
m∠C = x + 51

x + 3x+24 + x + 51 = 180
5x + 75 = 180
5x = 180 - 75
5x = 105
x = 105/5
x = 21

m∠A = x = 21°
m∠B = 3x+24 = 3*21 + 24 = 87°
m∠C = x + 51 = 21 + 51 = 72°
