Step-by-step explanation:
angle EAB = 2x too, due to the laws of the same and mirrored angles when a line crosses 2 parallel lines.
the angle ABE is 180 - 6x, due to the fact that all angles around a single point on one side of a line ad up to 180 degrees.
similarly, the angle AEB is 180 - 4x.
and then we know the sum of all angles in a triangle is airways 180 degrees.
so,
180 = 2x + 180 - 4x + 180 - 6x
0 = 180 - 8x
8x = 180
x = 22.5
Answer:
A(7,5)
Step-by-step explanation:
This is correct because the area of a triangle is b × h = a.
Answer:
Have You tried 150? :)
Step-by-step explanation:
Ok we can simplify the ratio 10 and 15 by dividing both terms by the greatest common factor which is 5 Ok. So 10 divided by 5 is 2 and 15 divided by 5 is 3 therefore the answer is 2 : 3
Answer:
a + 4b - 4
Step-by-step explanation:
Step 1: Write out expression
3a + 4b - 2a + 3 - 7
Step 2: Combine like terms (a)
a + 4b + 3 - 7
Step 3: Combine like terms (constants)
a + 4b - 4
