Answer:
D
Step-by-step explanation:
This is a 90 degree angle
90-35=55
X=11
35+5x=90
-35. -35
5x=55
Divide both sides by 5
X=11
Answer:
A
Step-by-step explanation:
A=hbb
2
Solving forhb
hb=2A
b=2·29.7
13.5≈4.4
Answer: 8
<u>Step-by-step explanation:</u>
EQ1: a + b + c = 2 --> b + c = 2 - a
EQ2: ab + bc + ac = -1 --> b + c = (-1 - bc)/a
EQ3: abc = -2 --> bc = -2/a
Set EQ1 = EQ2 and substitute bc using EQ3 to solve for "a":
Consider the solution a = 2 and plug it into EQ1 to solve for "b"
b + c = 2 - 2
b + c = 0
b = -c
Plug in a = 2, b = -c, and c = c into a³ + b³ + c³
2³ + (-c)³ + c³
= 8 - c³ + c³
= 8
To start, let's find the value of x as it gets closer to 0 from the positive side (we are working on the first example). To start, when x is 1, we have sin(2) - 2. This is approximately -1.965. Now, plugging in 2, we get (sin(4)-4)/8. This is -0.491. Now, we plug in 1/2 to get 8sin(1) - 8. This is approximately -7.86. Plugging in something like 1/1000, we will get -1965. Notice that there is no limit to it, so the answer is negative infinity, or DNE (IDK)
