Answer:
71°
Step-by-step explanation:
The equation should be 19+90+x=180
Step 1: Add 19+90=109
Step 2: Subtract 180-109=71
So, you're answer is 71°
Answer:
no solution
Step-by-step explanation:
24 + 6k < -6(-4-k)
Distribute
24+6k< 24 +6k
Subtract 6k from each side
24 < 24
This is never true so there are no solutions
The answer to the problem is as follows:
x = sin(t/2)
<span>y = cos(t/2) </span>
<span>Square both equations and add to eliminate the parameter t: </span>
<span>x^2 + y^2 = sin^2(t/2) + cos^2(t/2) = 1 </span>
<span>The final step is translating the original parameter limits into limits on x and y. Over the -Pi to +Pi range of t, x varies from -1 to +1, whereas y varies from 0 to 1. Thus we have the semicircle in quadrants I and II: y >= 0.</span>
You are multiply by 6 each time.
The next term is -216 x 6
-216 x 6= -1296
-1296 is your answer
hope this helps
