Answers

T is 71 degrees. We know this because the area of a triangle is 180 degrees, you add the angles given 27+82 which equals 109 then subtract that from 180 to find the missing angle “T” 180-109=71

Answer:

71 degrees

Step-by-step explanation:

The angles in a triangle add to 180 degrees, so

∠M + ∠A +∠T = 180

We know ∠M is 82 degrees, and ∠A is 27 degrees, so we can substitute them in.

82+27+∠T=180

109+ ∠T=180 Combine like terms by adding 82 and 27

109-109+ ∠T=180-109 Subtract 109 from both sides to get ∠T by itself

∠T=71

So, the m∠T is 71 degrees

Answers

Answer:

49 pi in^2 or approximately 153.86 in^2

Step-by-step explanation:

A = pi r ²

Let r = 7

A = pi 7 ²

A = 49 pi

If we approximate pi by 3.14

A is approximately 153.86 in^2

The answer is about 153.938

An equation is shown below:3(4x − 2) = 1

Which of the following correctly shows the first two steps to solve this equation?
Step 1: 12x − 2 = 1; Step 2: 12x = 3

Step 1: 12x − 6 = 1; Step 2: 12x = 7

Step 1: 7x + 1 = 1; Step 2: 7x = 0

Step 1: 7x − 5 = 1; Step 2: 7x = 6

Answers

Answer:

The correct option is 2.

Step-by-step explanation:

The given equation is

$3(4x-2)=1$

Step 1: use distributive property.

$3(4x)+3(-2)=1$

$12x-6=1$

Step 2: Add 6 on both the sides.

$12x-6+6=1+6$

$12x=7$

Therefore the correct option is 2.

Answer:

Ya'll trippin', the person above is correct, it's the second option;

Step 1: 12x - 6 = 1; Step 2: 12x = 7

Step-by-step explanation:

How do I know?

3(4x - 2) = 1

(do distributive property)

so 3 times 4x and 3 times -2

12x - 6 = 1

(add +6 to 1; you do + 6 because you do the opposite of the og sign)

12x = 7

SO, the answer is clearly the second option.
