Answer:
8.5
Step-by-step explanation:
To find √72, we must factor 72, remembering that the factor 36 is a perfect square:
√72 = √2·√36, or 6√2. Ashton failed to take the square root of the factor 2 of 72.
√72 = 6√2, and √2 is approx. 1.414.
Multiplying 1.414 by 6 results in 8.5, which is to the nearest tenth.
Because both angles are the same, and are in the same spot in the congruent triangles, we can set these angles up to equal each other:

Add x to both sides:

Subtract 4 from both sides:

Divide both sides by 4 to get x by itself:

The value of x is
17.

Answer: y=4
Step-by-step explanation:
9/4y-12=1/4y-4+12
+12. +12
9/4y=1/4y+8
-1/4y -1/4y
2y/2=8/2
y=4
