The triangle shown is an isosceles triangle, which means both the both angles are of the same size.

the sum of all the angles is 180°.

t ° + t ° + 110 ° = 180 °

2t ° = 180 ° - 110 °

2t ° = 70 °

t = 70°/2

t = 35 °

Answer:

<h2>35°</h2>

Step-by-step explanation:

This is an isoceles triangle

And as we all know an isoceles triangle has two equal base angles.

And we also know that the sum of all interior angles of the triangle is 180°

So based on this we can form an algebraic equation of solve for angke t (Let's do it :))

110 + 2t = 180 \\ 2t = 180 - 110 \\ 2t = 70 \\ t  =  \frac{70}{2}  \\ t = 35

So the base angle is 35°

What is the volume of this? PLEASE ANSWER,, answer choices are •213 •336 •288
enyata [817]

Answer:

288 cm³

Step-by-step explanation:

The volume (V) of the triangular prism is

V = area of triangular base × height

area of base = \frac{1}{2} × 6 × 8 = 24 cm², hence

V = 24 × 12 = 288 cm³

What is the equation for the line in slope-intercept form?
iris [78.8K]

Answer:

y = mx+b

Step-by-step explanation:

This is the equation for finding the slope-intercept form. Just plug in the numbers and you'll get your answer.

I know this doesn't give you the exact answer, but you have to figure things out on your own. It's good to get a little help, but not the direct answer.

What is the period of the graph of y=2 cos (pie/3 x ) +3<br> A.2<br> B.3/pie<br> C.6<br> D.pie/3
Tatiana [17]

Equate what is inside cosine with 2\pi, base period and solve for x,

2\pi=\frac{\pi}{3}x

6\pi=\pi x

\boxed{x=6}

Hope this helps :)

How much money does the average professional hockey fan spend on food at a single hockey​ game? That question was posed to 10 ra
Vinil7 [7]

Answer:

Now we have everything in order to replace into formula (1):

18-2.262\frac{2.75}{\sqrt{10}}=16.03    

18+2.262\frac{2.75}{\sqrt{10}}=19.97    

Step-by-step explanation:

Information given

\bar X=18 represent the sample mean

\mu population mean (variable of interest)

s=2.75 represent the sample standard deviation

n=10 represent the sample size  

Confidence interval

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

The degrees of freedom are given by:

df=n-1=10-1=9

The Confidence is 0.90 or 90%, the significance is \alpha=0.1 and \alpha/2 =0.05, and the critical vaue would be t_{\alpha/2}=2.262

Now we have everything in order to replace into formula (1):

18-2.262\frac{2.75}{\sqrt{10}}=16.03    

18+2.262\frac{2.75}{\sqrt{10}}=19.97
