12. For triangle MNP shown, find the value of x

amm1812

Answer:

$x=36\°\\\angle P=71 \°,\angle N=73 \°,\angle M=36 \°$

Step-by-step explanation:

Given:

The triangle is shown below.

We know that the sum of all interior angles of a triangle is equal to 180°.

Therefore,

$\angle M+\angle N+\angle P=180 \°\\\\x+2x+1+2x-1=180\°\\\\5x=180\°\\\\x=\frac{180}{5}\\\\x=36\°$

Now, plugging the value of 'x' in each angle measure and determining its values. We get:

$\angle M=x=36\°\\\angle P=2x-1=2(36)-1=72-1=71\°\\\angle N=2x+1=2(36)+1=72+1=73\°$

Therefore, the value of 'x' is 36° and the measure of the three angles are 36°, 71° and 73°.

What number must you add to the polynomial below to complete the square?<br><br> x2 + 15x

Aleksandr-060686 [28]

Answer:

The number $\frac{225}{4}$ is added to the polynomial below to complete the square.

Step-by-step explanation:

Perfect square binomial:

A perfect square binomial is given by:

$(a + b)^2 = a^2 + 2ab + b^2$

In this question:

We have that:

$a^2 + 2ab + b^2 = x^2 + 15x + ?$

Since $a = x$ , we have that:

$2ab = 15x$

$2b = 15$

$b = \frac{15}{2}$

Completing the square:

The term that completes the square is $b^2$ . So

$b^2 = (\frac{15}{2})^2 = \frac{225}{4}$

The number $\frac{225}{4}$ is added to the polynomial below to complete the square.

CA=2,AB=3, The angle of C=90 degrees what is the angle of B?

Levart [38]

Answer:

m∠B ≈ 41.81°

Step-by-step explanation:

If we draw a picture, it would help a lot. Once we visualize the triangle, we can see that we have sin∅ = 2/3. So, plugging into your calc,

sin∅ = 2/3

∅ = sin^-1(2/3)

∅ = 41.8103
