Answer:
x = -7
Step-by-step explanation:
<u>Step 1: Distribute</u>
1/3(24x - 54) = 11(x - 4) + 5
8x - 18 = 11x - 44 + 5
<u>Step 2: Solve for x</u>
8x - 18 = 11x - 44 + 5
8x - 18 - 11x + 18 = 11x - 39 - 11x + 18
-3x / 3 = -21 / 3
x = -7
Answer: x = -7

Answer:
Step-by-step explanation:
Triangle PQR is given to be a right triangle, so the Pythagorean Theorem can be used to determine that PQ is the hypotenuse.
It is given that x^2 + y^2 =z^2 in triangle ABC, so AB = PQ.
The information shows that the triangles are congruent because their three sides are congruent. Therefore, to show that triangle ABC is a right triangle, we can use corresponding parts of the congruent triangles to show that BCA is a right angle.
