Step-by-step explanation:
Use Sine rule.
Angle A + angle B + angle C = 180 (sum of angles in triangle)
Angle A + 90 + 42 = 180
Angle A + 132 = 180
Angle A = 180 - 132
= 48
X=-6
If you divide both sides by -5 5/5 is 0 & 20/5 is 4 the next step is to subtract 2 from both sides. -4-2 is -6
Answer:you didnt add the whole thing what is the following??
Step-by-step explanation:
Answer:
23
Step-by-step explanation:
Evaluate f(- 2) then substitute the value obtained into g(x)
f(- 2) = 3(- 2)² + 2(- 2) - 1 = 3(4) - 4 - 1 = 12 - 5 = 7 , then
g(7) = 4(7) - 5 = 28 - 5 = 23
Answer:
3 + 6 + 12 + 24 + ⋯ is the corresponding geometric series. The sum of a geometric series can be determined using the formula: = 1( − 1)
