No because the triangle’s angle is less than 90 degrees if it was a right angle triangle it would have a square marking the angle.

Hmmm the increase, wel is just the difference 367 - 312, which is 55.

now, if we take 312 to be the 100%, what is 55 off of it in percentage?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
312&100\\
55&p
\end{array}\implies \cfrac{312}{55}=\cfrac{100}{p}\implies p=\cfrac{55\cdot 100}{312}

How do I use slope and distance formulas to classify a quadrilateral
Brut [27]
You use the slope formula to classify a quadrilateral as a parallelogram or rectangle. you use the distance formula to see if it is a trapezoid.

Answer:

27 =x

Step-by-step explanation:

We can use proportions to solve this problem.  Put the side of the small triangle over the same side of the large triangle.

x+8          10

------- = -------------------

2x-5          14

Using cross products

14 (x+8) = 10 (2x-5)

Distribute

14x+112 = 20x-50

Subtract 14x from each side

14x-14x +112 = 20x-50-14x

112 = 6x-50

Add 50 to each side

112+50 = 6x-50+50

162 = 6x

Divide by 6

162/6 =6x/6

27 =x

What is the phase shift of y = sin(1/2 x - pi/2)?
meriva

Answer:

π

Step-by-step explanation:

The standard form of the sine function is

y = a sin(bx + c)

where a is the amplitude, period = \frac{2\pi }{b} and

phase shift = - \frac{c}{b}

here b = \frac{1}{2}, c = - \frac{\pi }{2}

phase shift = - \frac{-\frac{\pi }{2} }{\frac{1}{2} }

= \frac{\pi }{2} × 2 = π
