9*12=108
4*x=4x
so, 4x/108
4x=108
x=27
Answer:
a is equilateral and right, b is scalene and acute, c is equilateral and acute, d is isoseles and right, e is scalene and either acute or right, f is equilateral and acute, g is scalene and acute, and h is scalene and obtuse
Step-by-step explanation:
The rest of the question is the attached figure.
============================================
Δ AYW a right triangle at Y ⇒⇒⇒ ∴ WA² = AY² + YW²
And AY = YB ⇒⇒⇒ ∴ WA² = YB² + YW² → (1)
Δ BYW a right triangle at Y ⇒⇒⇒ ∴ WB² = BY² + YW² → (2)
From (1) , (2) ⇒⇒⇒ ∴ WA = WB →→ (3)
Δ CXW a right triangle at Y ⇒⇒⇒ ∴ WC² = CX² + XW²
And CX = XB ⇒⇒⇒ ∴ WC² = XB² + XW² → (4)
Δ BXW a right triangle at Y ⇒⇒⇒ ∴ WB² = XB² + XW² → (5)
From (4) , (5) ⇒⇒⇒ ∴ WC = WB →→ (6)
From (3) , (6)
WA = WB = WC
given ⇒⇒⇒ WA = 5x – 8 and WC = 3x + 2
∴ <span> 5x – 8 = 3x + 2</span>
Solve for x ⇒⇒⇒ ∴ x = 5
∴ WB = WA = WC = 3*5 + 2 = 17
The correct answer is option D. WB = 17
To multiply powers of the same base, add their exponents.
Add 5 and 2 to get 7.
- The first option <em><u>n⁷</u></em><em><u> </u></em>is the correct answer.
Answer:
The answer is C
Step-by-step explanation:
In these questions you have to remember crawl before you walk. So x First then y match up the coordinates (-4,9) and such and the answer should reveal itself.
