Answer:

B= 45

Step-by-step explanation:

A right triangle has one right angle that is equal to 90 degrees.

The other two angles will be 45 due to the fact that a triangle needs to have 180 degrees.

Hopes this helps.

Answer:

32.87°

Step-by-step explanation:

It is asking for the measure of angle B.

tanB=\frac{opposite}{adjacent}

tanB=\frac{4.2}{6.5}

Now you need to find the arctan because you want the angle. (make sure your calculator is in degree mode)

B= arctan(4.2/6.5)

angle B= 32.86867893°

Answer:

see explanation

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal

(a)

\frac{AB}{DE} = \frac{BC}{EF} , substitute values

\frac{AB}{17.64} = \frac{6.3}{13.23} ( cross- multiply )

13.23AB = 111.132 ( divide both sides by 13.23 )

AB = 8.4

(b)

\frac{DF}{AC} = \frac{EF}{BC}, substitute values

\frac{DF}{4.1} = \frac{13.23}{6.3} ( cross- multiply )

6.3DF = 54.243 ( divide both sides by 6.3 )

DF = 8.61

A die is rolled, what is the probability that a 3 or a 6 is obtained? P (3 or 6) = ___
Assoli18 [71]

Answer:

Step-by-step explanation:

The sample space in a  3  times die roll  =63=216.  

Now,  P(getting at least one 6)=1−P(getting NO 6).  

Probability of getting no  6  in a single die roll

=56.  

Thus probability of getting NO  6  in three die rolls

=56×56×56=125216.  

Therefore, the probability of getting at least one  6  

P=1−125216=91216.
