I can give you are summary of how to do it. UK geometry is somewhat different to US with regard to symbols used and names.
You need to prove that the 2 triangles BCE and ADE are congruent and then you can say that the sides are also congruent:- Sides BC and AD are equal (opposite sides of a parallelogram) Also < CBE = <ADE ( alternate angles) and < BCE = EAD ( alternate angles) So the triangles are congruent by 2 angles and the corresponding side, ( I think that would be ASA in the US).
Answer:
x = 49.0 degrees
Step-by-step explanation:
tan-1 =
tan-1 x =
tan-1 x = 1.15
x = 48.990
round to the nearest tenth:
48.990 = 49
<u>Answer:</u>
<h2>Romania</h2>
U.S: 272,648,000÷9,364,520= 29.12
<u><em>Step-by-step</em><em> </em><em>explaination</em></u>
US: 29.12 people per square km
Romania: 22,609,000÷237,391= 95.24
Romania: 95.24 people per square km
Ghana: 18,339,000÷237,553= 77.20
Ghana: 77.2 people per square km
Line A: 2x+2y=8 ⇒2y=-2x+8 ⇒ y=-x+4
Line B: x+y=3 ⇒y=-x+3
Therefore: y=y then:
-x+4=-x+3
-x+x=3-4
0≠-1 ⇒There is no solution because the lines are parallels
Answer: There is no solution
