Question

Please help me! Geometry!

Answer 1

7. Find the value of x for which l is parallel to m. The diagram is not to scale.

Answer 2

A. 28
B. 56
C. 84
D. 152

Answer 3

@phi please help

Answer 4

http://www.mathsisfun.com/geometry/alternate-interior-angles.html any ideas?

Answer 5

28?

Answer 6

yeap

Answer 7

so it = 84 or u dont add them?

Answer 8

nope.... the 56 degrees doesn't correlate to the "x" angle...... in this case

Answer 9

so its just 28?

Answer 10

yeap

IF x = 28 degrees
then it becomes equal to its alternate interior angle up above and thus the lines are indeed parallel

Answer 11

will u help me with a few more questions?

Answer 12

notice in the example at http://www.mathsisfun.com/geometry/alternate-interior-angles.html c = f and d = e
ONLY IF the "orange lines" are parallel

Answer 13

4. Find m<Q (1 Point)
A. 76
B. 104
C. 66
D. 114

Answer 14

you can always post anew if I dunno someone elese may
and we can revise each other

Answer 15

anyow for Q -> http://www.mathsisfun.com/geometry/vertical-angles.html

Answer 16

76?

Answer 17

hmmm actaully for Q should be h http://www.mathsisfun.com/geometry/alternate-exterior-angles.html

Answer 18

I am thinking either A or C

Answer 19

hmmm any ideas on what R might be?

Answer 20

76?

Answer 21

ohh r

Answer 22

R = 76 and then Q = 66?

Answer 23

yeap

so we can say that

recall that there are only 360 degrees if you go around

so we have 76 = R or 76 + 76 + Q + ? = 360

BUT Q and ? are both equal to each other since they're vertical angles

or Q = ? so we can say that

\(\bf 76+76+Q+\square =360\implies 152+Q+\square=360
\\ \quad \\
Q+\square=360-152\qquad {\color{brown}{ Q=\square \implies 2Q}}\implies 2Q=360-152
\\ \quad \\
Q=\cfrac{360-152}{2}\)

Answer 24

\(\bf Q=\square \implies
\begin{cases}
Q+\square \implies Q+Q\implies 2Q
\end{cases}\) just to clarify

Q + "its vertial angle" are equal

Answer 25

Q = "its vertial angle" thus that'd be the same as saying Q + Q which is 2Q

Answer 26

q is 38

Answer 27

i think

Answer 28

76 + 76 + q(140) + 104 = 360

Answer 29

lemme see if I can put it differently
