Answer:
c) 82
Step-by-step explanation:
<ABE and <BEC are supplementary because they form a line.
<ABE + <BEC = 180
116+ x = 180
Subtract 116 from each side.
116-116+x = 180 -116
x = 64
The angles in triangle ECB add to 180 because it is a triangle
<BEC + <ECB + <CBE = 180
x + 34+y = 180
64 + 34+ y = 180
98 + y = 180
Subtract 98 from each side.
98-98+y = 180-98
y = 82
Answer:
AB =7 and CD = 7
BC =4 and AD =4
Step-by-step explanation:
A( 1,3)
B (1,10)
C (5,10)
D (5,3)
As we can see in the graph, the AB = CD and BC = AD
AB = the distance between the y points since the x values are the same
AB = 10-3 = 7
AB =7 and CD = 7
BC = the distance between the x points since the y values are the same
BC = 5-1 =4
BC =4 and AD =4
I believe the answer is 87%
Answer:
5
Step-by-step explanation:
divide the figure as a triangle and a rectangle first.
take away the rectangle part and if you just look at the triangle part,
you can get x using Pythagorean theorem.
Pythagorean theorem is a^2 + b^2 = c^2,
so 3^2 + 4^2 = x^2.
If you calculate it, x should be root 25, which equals 5.
So, the answer is 5.
First you distribute -3: x-29=-9-3x
then you add 3x on both sides: 4x-29=-9
then you add 29 on both sides: 4x=20
divide 4 in both sides: x=5
Answer: x=5
