Cos(x°) = (√3)/2
cos⁻¹[(√3)/2] = x°, that means x° = 30°

Step-by-step explanation:
Answer:
Step-by-step explanation:
4/7 x + 70 cm^3 = 3/4 x Subtract 4/7 x from both sides
3/4 x - 4/7 x = 70 cm^3 The lowest common denominator is 28

5x = 70*28
5x = 1960 Divide by 5
x = 1960/5
x = 392 cc
Answer:
3b^7a^6c^9/64
Step-by-step explanation:
Y - 3 = 8/3(x + 2)...the slope here is 8/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular line will have a slope of -3/8
y - y1 = m(x - x1)
slope(m) = -3/8
(-2,3)....x1 = -2 and y1 = 3
now we sub
y - 3 = - 3/8(x - (-2)...not done yet
y - 3 = -3/8(x + 2) <===
