The answer is 1/4 x - 3 = 12
Answer:

Step-by-step explanation:
In order to find the measure of angle KMI, we need to note some angle relationships here.
GK and HJ are parallel lines cut by a transversal, meaning the angles formed by this transversal line will be the same along the parallel lines.
We know that the 29° angle is an alternate interior angle to KMI. This means their angle measures are the same.
Therefore, KMI is also 29°.
Hope this helped!
Answer:
99 degrees
Step-by-step explanation:
81+a=180, so
180-81=99
a=99
For #4, for any right triangle a^2 + b^2 should equal c^2. Square roots are just numbers to a power of 1/2. You can multiply the exponents together of #^(2 * 1/2) and simply get #. With that in mind, we can use sqrt2 as our a, sqrt3 as b, and sqrt5 as c, since c is always the largest number. For A, sqrt2 squared is 2, for B, sqrt3 squared is 3, and c is 5. Since 2+3 does indeed equal 5 you have a right triangle.
For #5, dilating by 3 means our length will be three times as long as whatever it is there. To find out how long the line is, we can make a right triangle. The differences between the x values are 6, and the differences between the y values are 12. A^2 + b^2 = c^2, 144 + 36 = 180, c= sqrt180, which is approx. 13.416. Multiply that by 3 and you get ≈40.25 as K’L’.
