Answer:

x = 37°

Step-by-step explanation:

Given the triangle with two given exterior angles, m ∠107° and m ∠110°:

We can use the <u>exterior angle theorem</u> where it states that the measure of each exterior angle of a triangle is equal to the sum of the measures of the opposite and remote interior angles.

Start by finding the supplement of m ∠110°, that will serve as the other remote interior angle.

The supplement of ∠110° is:

∠110° + y  = 180°

Where y = represents the other unknown interior angle.

Subtract ∠110° from both sides:

∠110° - ∠110°  + y  = 180° - ∠110°

y =  70°

Therefore, the other remote interior angle is y = 70°. Now, we can determine the value of x by establishing the following equation:

107° = x° + 70°

Subtract 70 from both sides:

107° - 70° = x° + 70°- 70°

x = 37°

Answer:

<h3>1863 m squared</h3>

Step-by-step explanation:

So, the goal here is to find the area of each block individually then add it all together. In other words, you're gonna look for a way to solve for the missing square in the total large rectangle. Keep in mind 23 + 23 + 23 = 69 (aka the length of the whole rectangle)

So:

12 x 23 = the missing square = 276

31 x 69 = rectangle with the square = 2139

Total area = 2139 - 276 = 1863

Answer:

The Answer is: x / y = 8 / 3

Step-by-step explanation:

3(x - 2) - 4(2y - 1) + 2=0

3x - 6 - 8y + 4 + 2 = 0

3x - 8y = 0

3x = 8y

3x/y = 8

x / y = 8 / 3

Hope this Helps! Have an Awesome Day!! (-:
