Use the formula: (a+b)(a-b) = a^2 - b^2
No matter what the value of 'x' is, the final answer will always be
1.
Answer:
s = 5/4
Step-by-step explanation:
Solve for s:
86 = 8 s + 76
86 = 8 s + 76 is equivalent to 8 s + 76 = 86:
8 s + 76 = 86
Subtract 76 from both sides:
8 s + (76 - 76) = 86 - 76
76 - 76 = 0:
8 s = 86 - 76
86 - 76 = 10:
8 s = 10
Divide both sides of 8 s = 10 by 8:
(8 s)/8 = 10/8
8/8 = 1:
s = 10/8
The gcd of 10 and 8 is 2, so 10/8 = (2×5)/(2×4) = 2/2×5/4 = 5/4:
Answer: s = 5/4

Answer: Like the angles BAC (56°) and BDC has the same arc BC in the circumference, these angles must be congruent, then angle BDC must be equal to 56°.
