Answer:
g = 3.5
f = 78°
<u>Finding</u><u> </u><u>g</u><u>:</u>
25 is parallel to 8g - 3, so they are equal to each other.
25 = 8g - 3
28 = 8g
g = 3.5
<u>Finding</u><u> </u><u>f</u><u>:</u>
72° create a sum of 180° when adding to (f + 30) because they are supplementary.
72 + f + 30 = 180°
102 + f = 180°
f = 78°
Hope this helps!
Answer:
Step-by-step explanation:
- a. -9+2, in this case, it is -7 because you take the bigger number and subtract it by the lower number. If the bigger number is negative your answer will be negative, if the bigger number is positive it will be positive it is just really a basic subtraction problem just add the sign.
- b. In multiplication +++=+ ++-=- and a -+-=+ do your problem without thinking about the signs and then add the signs with the formula I showed you.
Hope this helps :)!
Hello from MrBillDoesMath!
Answer:
@ = pi/3 (or 60 degrees) or @ = 7 pi/3 (or 420 degrees)
Discussion:
Let "@' denote the angle "theta". We are asked to find @ in the interval [0, 4 pi)
where
4cos(@) - 2 = 0. Adding 2 to both sides
4 cos(@) - 2 +2 = 2 =>
4 cos(@) = 2 Divide both sides by 4
cos(@) = 2/4 = 0.5
This implies that @ = pi/3 (or 60 degrees) or @ = (pi/3 + 2pi) = 7 pi/3 (or 420 degrees)
Thank you,
