PV = 8 VT = 4√3
Step-by-step explanation:
Given
PT = 4
With reference angle 30°
perpendicular (p) = 4
hypotenuse (h) = ?
sin 30° = p/h
1/ 2 = 4 / h
cross multiply
h = 8
with reference angle 60°
perpendicular (p) = ?
hypotenuse (h) = 8
sin 60° = p/h
√3 / 2 = p / 8
Cross multiply
2p = √3 * 8
p = 4 √3
Answer:
y = x - 2
Step-by-step explanation:
1. Find the slope - change in y/change in x
= 1
Slope is 1
2. Find y-intercept
y = x + b
Substitute a point (2,0)
0 = 2 + b
b = -2
3. Put the equation together
y = x - 2
Is that in a different language?
Answer:
2x + 2y + 2
Step-by-step explanation:
x+ 2y + x +2 (combine like terms)
x + x + 2y + 2
2x + 2y + 2
Answer:
Step-by-step explanation:
(-5)^2 - (-5^2)
25 - (-25)= 25 + 25 = 50
