A: D. m1 + m2 = m3

the exterior angle of a triangle is equal to the sum of the other 2 interior angles

B: 36 deg

plug in the equations given to find m1:

(5x + 11) + (3x+22) = (9x+28), solve for x to get x=5

plug x=5 into the equation for m1 to get 5*5 +11 = 36degrees

otez555 [7]

Answer:

Given,

The total distance covered = 4 km,

Since, initially he would be in rest,

So, his starting point would be 0.

Now, his first break = \frac{4}{3} km,

Second break = \frac{10}{3} km,

Also, we can write,

4=\frac{4\times 3}{3}=\frac{12}{3}

Drawing number line:

Step 1: Draw a line.

Step 2: Make 12 marks in same distance.

Step 3: Starts from 0, then 1/3, 2/3, 3/3 and so on.

Thus, we can show Wayne's bike on a number line as below.

Please please help me, I don’t understand at all, I will truly appreciate it! Thank you

The answer is A.

y = x^2 + 2 simply means that y is whatever x is to the second power, plus 2. so, -2^2 = 4. 4 + 2 = 6.

you can work this through the other options but A is the answer.
