Answer: B. Andy is incorrect, because more than one triangle can be drawn with the given information.

Step-by-step explanation:

Given: Andy wrote the following statement:

"You can only draw one unique isosceles triangle that contains an angle of 55°."

In isosceles triangle, there are two equal angles and one non-equal angle.

So, there is possibility of many isoceles triangles with 55°. It can be the measure of equal angles or non- equal angles.

hence, B is the right option. Andy is incorrect.

I believe it would be B. Because, an isoceles triangle is a triangle with 2 equal sides and 1 is not equal ... SO, more than one triangle could be drawn from this information. Because, 55 could be the uneven side for many triangles. So, B. Andy is incorrect, because more than one triangle can be drawn from the given info. :)

<u><em>B.</em></u><em /> Hope it helps!!! :)<em /><em />

Find the measure of the missing angles in the triangle below round your answer to the nearest degree

navik [9.2K]

Answer:

a. 40°

b. 21°

Step-by-step explanation:

a. Reference angle = θ

Opposite = 5

Adjacent = 6

Apply TOA:

$Tan (\theta) = \frac{Opp}{Adj}$

$Tan (\theta) = \frac{5}{6}$

$\theta = Tan^{-1}(\frac{5}{6})$

$\theta = 40$ (nearest degree)

b. Reference angle = x

Opposite = 5

Hypotenuse = 14

Apply SOH:

$Sin (x) = \frac{Opp}{Hyp}$

$Sin (x) = \frac{5}{14}$

$x = Sin^{-1}(\frac{5}{14})$

$x = 21$ (nearest degree)

If an object is dropped from a height of 55 feet, the function d = -16^2 + 55 gives the height of the object after t seconds. Gr

motikmotik

Answer:

Approximately 1.9 seconds (correct to nearest tenth)

Step-by-step explanation:

Looks like the function is d = -16t^2 + 55 ( you left out the t)

The answer is the value of t when d = 0 so we have the equation:-

0 = -16t^2 + 55

16t^2 = 55

t^2 = 55/16

t = sqrt (55/16)

= 1.85 seconds

The area of another rectangle is x² + 5x + 6. If one side measures (x + 2), what is the measure of the other

tiny-mole [99]

L=x+2
We need B

$\\ \sf\longmapsto LB=Area$

$\\ \sf\longmapsto B(x+2)=x^2+5x+6$

$\\ \sf\longmapsto B(x+2)=(x+2)(x+3)$

Cancel x+2

$\\ \sf\longmapsto B=x+3$

Harry's parrot is 11 years older than his cat.

Sav [38]

Answer:

The answer to your question is: P = 17 years

Step-by-step explanation:

Data

Parrot = 11 years older than the cat

C = cat age

P = parrot age

P = ? when C = 6

Process

P = C + 11

P = 6 + 11

P = 17 years
