The three inside angles of a triangle need to equal 180 degrees.
To find X subtract the two known angles from 180.
X = 180 - 45 - 70
X = 65 degrees.
Answer:

Step-by-step explanation:
keep, change, flip
2/1 (keep) x (change to multiply) 5/2(2/5 flips to 5/2)
2/1 x 5/2
10/2

Answer:
200 feet to 2 ft 6 inches (or 30 inches)
Convert the 200 feet to inches
2400 inches.
2400 divided by 30 inches is
80 inches per feet
600 inches divided by 80 is
7.5 inches rounded up is 8 inches
the answer is 8 inches
Step-by-step explanation:
If you convert feet to inches, 1 ft = 12 in
2 feet * 12 inches = 24 in
That means 2 ft is greater than 23 in.

<h2>
Step-by-step explanation:</h2>
We will use the Gaussian elimination method to solve this problem. To do so, let's follow the following steps:
Step 1: Let's multiply first equation by −2. Next, add the result to the second equation. So:

Step 2: Let's multiply first equation by −1. Next, add the result to the third equation. Thus:

Step 3: Let's multiply second equation by −35, Next, add the result to the third equation. Therefore:

Step 4: solve for z, then for y, then for x:


By substituting
into the first equation, we get the
. So:
