Complete Question

Triangle ABC has the angle measures shown. Measure of angle A = (2 x) degrees. Measure of angle B = (5 x) degrees. Measure of angle C = (11 x) degrees.

Which statement is true about the angles?

a) Measure of angle A = 20 degrees

b) Measure of angle B = 60 degrees

c) Angle A and Angle B are complementary

d) Measure of angle A + measure of angle C = 100 degrees

Answer:

a) Measure of angle A = 20 degrees

Step-by-step explanation:

It is known that the sum of angles in a triangles = 180°

We are given these values in the question

Triangle ABC has the angle measures shown. Measure of angle A = (2 x) degrees. Measure of angle B = (5 x) degrees. Measure of angle C = (11 x) degrees.

Therefore,

Angle A + Angle B + Angle C = 180°

2x + 5x + 11x = 180°

18x = 180°

x = 180°/ 18

x = 10°

Finding each of the angles

Angle A = 2x = 2 × 10 = 20°

Angle B = 5x = 5 × 10 = 50°

Angle C = 11x = 11 × 10 = 110°

Therefore, the correct option is:

a) Measure of angle A = 20 degrees

What is Ratios? I am having a hard time understanding what they are.

lesya [120]

Answer:

In mathematics, a ratio indicates how many times one number contains another

so lets say you have 2 to 4 that is equivalent to the ratio 1 to 2, that is 2:4 = 1:2. Note also that a fraction is a number that stands for "part of something", so although this ratio can be expressed as a fraction, in this case it does NOT represent "part of something".

Note that the ratio 2 to 4 is said to be equivalent to the ratio 1 to 2, that is 2:4 = 1:2. Note also that a fraction is a number that stands for "part of something", so although this ratio can be expressed as a fraction, in this case it does NOT represent "part of something".

Step-by-step explanation:

If you dont know what equivalent means i will define it

Its like a diviosn problem lets say you have 10/20 to make that a equlivant fravtion you need to divide the top number and the bottom number (numberator and denominator) by the sme number 10/20 ca both be divided by 10 ,so 10 divided by 10 is 1 and 20 divided by 10 is 2 so the new fraction is 1/2.

(10/20=1/2)

Hope that makes sense lol.

Multiply the polynomials.<br> (3x2 + 4x + 4)(x-4)

aksik [14]

Multiplication of two polynomials $\left(3 x^{2}+4 x+4\right) \text { and }(x-4) \text { is } 3 x^{3}-8 x^{2}-12 x-16$

<u>Solution:</u>

Need to multiply following polynomial

$\left(3 x^{2}+4 x+4\right)(x-4)$

$\text { Lets for sake of simplicity }\left(3 x^{2}+4 x+4\right)=\mathrm{A}$

$\text { So }\left(3 x^{2}+4 x+4\right) \times(x-4)=\mathrm{A} \times(x-4)=\mathrm{A} \times(x)-\mathrm{A} \times 4$

$\text { Now again substitute value of } \mathrm{A} \text { as }\left(3 x^{2}+4 x+4\right)$

$=>\left(3 x^{2}+4 x+4\right) \times(x-4)=\left[\left(3 x^{2}+4 x+4\right) \times(x)\right]-\left[\left(3 x^{2}+4 x+4\right) \times 4\right]$

On opening the internal brackets we get,

$\begin{array}{l}{\Rightarrow\left(3 x^{2}+4 x+4\right) \times (x-4)=\left[3 x^{3}+4 x^{2}+4 x\right]-\left[12 x^{2}+16 x+16\right]} \\\\ {\Rightarrow\left(3 x^{2}+4 x+4\right) \times (x-4)=3 x^{3}+4 x^{2}+4 x-12 x^{2}-16 x-16}\end{array}$

On bringing similar terms together, we get

$\begin{array}{l}{=>\left(3 x^{2}+4 x+4\right) \times (x-4)=3 x^{3}+4 x^{2}-12 x^{2}+4 x-16 x-16} \\ {=>\left(3 x^{2}+4 x+4\right) \times (x-4)=3 x^{3}-8 x^{2}-12x-16}\end{array}$
