7x - 5 = 30
* add 5 to both sides
7x = 30 + 5
7x = 35
* divided both sides by 7
(7/7)x = 35/7
<u><em>x = 5</em></u>
Answer:
(6^4 x 2^-9)
Step-by-step explanation:
Answer: 63 degrees.
1. The Vertical Angles Theorem marks “x” as equivalent to its opposite angle (Angle A).
2. Angle A is apart of a 90-45-45 right triangle (since Angle B is 90 degrees).
3. Angle A and C are equivalent because of the 45-45-90 relationship.
4. Angle C is the vertical angle of the angle measuring 63 degrees.
5. So Angle X=Angle A=Angle C= 63 degrees.
Part 1) The value of x is 5
Part 2) The length of line AB is 5 inches
Part 3) The length of BC is 15 inches
