Answer:
B
Step-by-step explanation:
You can rule out all others. A is wrong because a triangle cannot be acute and obtuse at the same time. C is wrong because a polygon dosen't neccassarily need to be a triangle, for example, a polygon is a closed shape, so it could be a rectangle. It isn't D because there are obtuse triangles out there. So, the only one left is B.
<span>The correct answer for the question that is being presented above is this one: " Your trying to figure out what is 48 percent of 70 because that's how much Adam's sister is going to eat at dinner. So your is would be 48 and your of is 70. When you substitute those numbers your formula becomes 48/70=x/100. Now you cross multiply and get 70x=4800.All that's left is to divide 70 on both sides. Which gives you 68.57.The final answer is 69 percent."</span>
Answer:
x=
−1
/2
y+
3
/4
Step-by-step explanation:
Let's solve for x.
4x+2y=3
Step 1: Add -2y to both sides.
4x+2y+−2y=3+−2y
4x=−2y+3
Step 2: Divide both sides by 4.
4x
/4
=
−2y+3
/4
x=
−1
/2
y+
3
/4
cos (90° - x) should be the answer
