Answer:
x=6
y=-5
Step-by-step explanation:
3x+2y=8 equation 1
x-2y=16 equation 2
equation 2+equation1 ; 4x = 24
x = 6
substitution x in equation1 ;
18+2y=8
2y = -10
y = -5
The correct answer for the question that is being presented above is this one: "C 6 in. by 8 in. by 10 in. The dimension of the rectangular prism container is 6 in. by 8 in. by 10 in.
Here are the following choices:
<span>A <span>3 </span><span>in. by </span><span>8 </span><span>in. by </span><span>10 </span>in.</span><span><span>B </span><span>6 </span><span>in. by </span><span>4 </span><span>in. by </span><span>12 </span>in.</span><span><span>C </span><span>6 </span><span>in. by </span><span>8 </span><span>in. by </span><span>10 </span>in.</span><span><span>D </span><span>8 </span><span>in. by </span><span>4 </span><span>in. by </span><span>8 </span>in.</span>
Answer:1
1. 
2. ∠ABC = 120°, ∠BCD = 90°, ∠CDA = 60°, ∠DAB = 90°
Step-by-step explanation:
It's important to note here that the measure of all interior angles in a quadrilateral will add up to 360°
We know this using the formula
, a 4 sided figures angles will add up to
This means that all of the angles (4x, 3x, 2x, 3x) will add up to 360.
Combine like terms:
Divide both sides by 12:
We know now substitute x for 30 in for all of the side lengths.
∠ABC = 4x = 
°
∠BCD = 3x = 
°
∠CDA = 2x = 
°
∠DAB = 3x = °
Hope this helped!
