Answer:
<em>c</em> = 32.1
<em>b = </em>34.4
<em />
47 degrees
Step-by-step explanation:
Using sine = opp/hyp. to find side c:
Using cosine = adj/hyp. to find side b:
Finding angle B:
It's a right triangle and you're given one of the acute angles, which means you can find the missing third angle. All triangles interior angles add to equal 180 degrees.
180 - (43 + 90) = 47 degrees
Since x+y equals 5 that means x is 3 and y is 2 because 3+2=5. So now plug it in, 2(3)+3(2). Two multiplied by three is 6 and three times two is 6. So now it’s 6+6 which equals 12. So it’s 2(3)+3(2)=12
You can split this into 2 shapes.
1 of the shapes will be a small square. The dimensions for it would be 4 by 3 (12)
The second shape, the bigger rectangle has the dimensions, 12 by 6 (72)
Now add these two values 12+72 and you get, 84
you answer is A 84 square inches
20/42 + 14/42 - 8/42 = 26/42
