Answer:
32
Step-by-step explanation:
Area = a+b/2 * h
6+10/2= 8
8*4 = 32
Answer:
The answer for this problem is at the bottom of picture.
Answer: A
Step-by-step explanation:
If the fraction is negative, and the numerator and denominator is negative, then if you were to do anything to them it would become a positive
Answer: see proof below
<u>Step-by-step explanation:</u>
Given: A + B + C = π → A + B = π - C
→ B + C = π - A
→ C + A = π - B
→ C = π - (B + C)
Use Sum to Product Identity: cos A + cos B = 2 cos [(A + B)/2] · cos [(A - B)/2]
Use the Sum/Difference Identity: cos (A - B) = cos A · cos B + sin A · sin B
Use the Double Angle Identity: sin 2A = 2 sin A · cos A
Use the Cofunction Identity: cos (π/2 - A) = sin A
<u>Proof LHS → Middle:</u>
LHS = Middle
<u>Proof Middle → RHS:</u>
Middle = RHS
8 / x = 12 - 3(8)
8 / x = 12 -24
8 / x = -12
x = -0.66666666667
Check your work
8 /(-0.66666666667) = 12- 3(8)
-12 = 12 - 3(8)
-12 = -12
x = -0.66666666667 Exactaly (Ten 6's One 7)
Hope this helps :)
