Answer:

b = 1.7

c = 7.1

Step-by-step explanation:

the triangle with side 'b' is a 30-60-90° Δ where the ratio of sides, respectively, are 1 : \sqrt{3} : 2

to find 'b' we could set up this proportion:

b/3 = 1/\sqrt{3}

cross-multiply:

b\sqrt{3} = 3

b = 3 / \sqrt{3}

if we rationalize the denominator, this becomes (3\sqrt{3})/3 which is \sqrt{3} or 1.7

the other triangle is a 45-45-90°Δ where the ratio of the sides are 1 : 1 : \sqrt{2}

if the legs are 5 then the hypotenuse is 5\sqrt{2} or 7.1

Can someone plz help I do not know what I am doing
PolarNik [594]

the answer is D-n is greater then or equal to nine.

because the red dot starts on nine and goes up its greater than nine and because its on nine its also going to equal it. I had a problem getting the signs messed up when I learned it but I remember the sign always eats the greater number. I hope this answer could help and I'm sorry if the answer is incorrect.

Find the values for x and y
USPshnik [31]

Answer:

x = 55

y = 70

Step-by-step explanation:

Since all three sides are equal, as indicated by the lines on the sides, all three angles are equal

Since a triangle is equal to 180 degrees

180/3 = 60

Each angle is 60 degrees

x+5 = 60

Subtract 5 from each side

x +5-5 = 60-5

x = 55

y-10= 60

y-10+10 = 60+10

y= 70

Find the percent of increase from 1.5 inches to 6 inches.
Komok [63]
Well, from 1.5 to 6 is a 4.5 difference.

now, if we take 1.5 to be the 100%, what is 4.5 off of it in percentage?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1.5&100\\
4.5&p
\end{array}\implies \cfrac{1.5}{4.5}=\cfrac{100}{p}\implies p=\cfrac{4.5\cdot 100}{1.5}
