Answer:
x = <u>16</u> units
Step-by-step explanation:
∆ABC is a 45-45-90 triangle, and ∆BCD is a 30-60-90 triangle.
If side opposite of 90° [∆] = x, side opposite of 45° [∆] = x / √2 = x √ 2 / 2.
Given side AC is opposite of 90° [∆ABC] = 32 √ 2, side opposite of 45° [∆ABC] = 32 √ 2 / √ 2 = 32 which is AB or BC.
Since side BC is part of BCD.
Side opposite of 90° [∆BCD] = BC = 32.
Since x is opposite of 30° [∆BCD].
x = Side opposite of 90° [∆BCD] / 2 = 32 / 2 = 16.
The answer to this question is going to be letter B
Answer: 3
Step-by-step explanation: This is because the 2 numbers are opposites, which cancel each other out, going back to zero.
7^6/7^2
(7*7*7*7*7*7)/(7*7)
the answer is b. 7^4
Option B is correct
Why
3x=21
3(7) =21
21=21
