Answer:

Step-by-step explanation:

because this is an isoscele triangle this means that the angles from the base are congruent what mean that than one angle has measure of 54 degree - given - so the second angle from the base has a measure of 54 degree too

we know that the sum of angles of a triangle is equal 180 degrees so the vertex angle has a measure of 180 -(54+54) = 180 -108 = 72 degrees

Roman55 [17]

Answer:

Option B.

Step-by-step explanation:

The given triangle is a right angle triangle.

In a right angle triangle,

$\tan \theta=\dfrac{Perpendicular}{Base}$

In the given triangle,

$\tan (45^{\circ})=\dfrac{v}{7}$

$1=\dfrac{v}{7}$

$7=v$

Using Pythagoras theorem, we get

$hypotenuse^2=Perpendicular^2+Base^2$

$u^2=v^2+7^2$

$u^2=7^2+7^2$

$u^2=2(7^2)$

Taking square root on both sides, we get

$u=\sqrt{2(7^2)}$

$u=7\sqrt{2}$

Therefore, the correct option is B.

What polynomial has roots of −5, −4, and 1?

katrin [286]

Answer:

The last choice.

Step-by-step explanation:

The last term is - 20 and because we have a coefficient of 1 on the x^3, and in order to get this last term and the given roots the factors have to be

(x + 5)(x + 4)(x - 1) so it is the last option.

How do you divide 3/8 by 6/7 in simplest form

Ipatiy [6.2K]

Answer:

7/16

Step-by-step explanation:

First, it is good to know that when you divide fractions, you are multiplying it's reciprocal.

6/7's reciprocal is 7/6, since the reciprocal is $\frac{1}{6/7}$

3/8 / 6/7 =

3/8 * 7/6

Now that we have that, we can just multiply the two:

3/8 * 7/6 =

21/48 =

7/16

Hope this helped :)
