Drag an answer to each box to complete this paragraph proof. Given: Triangle ABC Prove: m/A= 66 A B (5x) By the C (x + 10) m/A+m

/B +m/C= 180°. Using the the sum of the angles in a triangle is equal to 180°. Therefore, solve for x, first combine like terms to get 6x + 100 = 180. Using the (5x) +90° + (x + 10) = 180°. To 6x = 80. Then, using the division property of equality, x = 13. To find the measure of angle A, use the substitution property to get m/A = 5(13). Finally, simplifying the expression gets mA = 663"​

The value of A has been illustrated, computed and proven based in the triangle given.

<h3>How to calculate the triangle?</h3>

It should be noted that that a triangle is a shape that has three sides and the value of the addition of all the angles are equal to 180°.

Based on the information that's given, it should be noted that the value of angle A, angle B, and angle C will be equal to 180°.

In this case, the following can be deduced:

A = 5x

B = 90°

C = x + 10°

Therefore, A + B + C = 180° (sum of angles in a triangle)

5x + 90 + x + 10 = 180°

6x = 180° - 90° - 10°

6x = 80°

x = 80/6

x = 13 1/3

Therefore, the value of A will be:

= 5x

= 5 × 13 1/3

= 66 2/3

Therefore, A is 66 2/3.

Which shows one way to determine the factors of 12x3 – 2x2 18x – 3 by grouping?.
Ksenya-84 [330]

The equation which shows the one way to determine the factors of provided equation by grouping is,

2x^2(6x-1)+3(6x-1)

<h3>What is a factor of polynomial?</h3>

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

Factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.

The provided polynomial equation is,

12x^3 - 2x^2 +18x - 3

To factorize the above polynomial equation, make the groups, by taking out the greatest common factor.

12x^3 - 2x^2 +18x - 3\\2x^2(6x-1)+3(6x-1)\\(6x-1)(2x^2+3)

Hence, the equation which shows the one way to determine the factors of provided equation by grouping is,

2x^2(6x-1)+3(6x-1)

Pls pls help i will mark brainliest to whoever can answer it for me.
Luba_88 [7]

Answer:

The lateral surface is 120  in^2, which agrees with the third answer option of the list.

Step-by-step explanation:

Notice that the prism has 5 equal lateral faces, which are all rectangles of eight 6". The width of the prisms can be obtained by using the fact that the perimeter of the pentagon is 20", which gives a side length of 20/5 = 4 " which is the same as the with of the lateral rectangles.

Then the lateral area of the prism is:

Lateral area= 5 (6" x 4") = 5 (24) =  120 in^2
