what is ur question?

OpenStudy (anonymous):

i posted a picture

OpenStudy (anonymous):

ok... i am trying! do u know the relation between angular and it's front line?!

OpenStudy (anonymous):

no

OpenStudy (anonymous):

the answer is 37 :)

OpenStudy (anonymous):

how do you know?

OpenStudy (anonymous):

we can find y and x easily! and after that, we realize that 2 triangles are same. so the angular near 53 is 53 too. after this u see the bigger triangle contains two triangle. sum of the angulars should be 180 and we find one of them (53+53=106). 180-106=74 74 is sum of the another triangles. both of them should be same. so each of them should be 37 (74/2). ok?

Unit 6 Lesson 6 1. Classify the figure in as many ways as possible. (1 point) (1 pt) rectangle; square; quadrilateral; parallelogram; rhombus (0 pts) rectangle; square; parallelogram (0 pts) rhombus; quadrilateral; square (0 pts) square; rectangle; quadrilateral 1 /1 point 2. Which statement is true? (1 point) (0 pts) All quadrilaterals are rectangles. (0 pts) All quadrilaterals are squares. (1 pt) All rectangles are quadrilaterals. (0 pts) All quadrilaterals are parallelograms. 1 /1 point 3. Lucinda wants to build a square sandbox, but she has no way of measuring angles. Which of the following explains how she can make sure the sandbox is square by measuring only length? (1 point) (0 pts) Arrange four equal-length sides, so the diagonals bisect each other. (1 pt) Arrange four equal-length sides, so the diagonals are equal lengths also. (0 pts) Make each diagonal the same length as four equal-length sides.

What about the short answers?

OpenStudy (anonymous):

Hope that helps

OpenStudy (anonymous):

I would post all of Unit 6 Lesson 6 but that would take forever because it is a quiz and I cant just copy and paste

OpenStudy (anonymous):

i sure that there is a relation between angels and the front line. but i cant find it at the moment... i will give u later;)

OpenStudy (anonymous):

What short answers? Do you mean for the quiz

OpenStudy (anonymous):

here is #11 Opposite sides are equal in a rhombus side AD = side BC side AB = side DC side AC = side AC These two trianlges are congruent by SSS

OpenStudy (anonymous):

#10 y-4=x+5 y=x+9 2x+5=x+12 x+5=12 x=7 (7+9)-4=12 16-4=12 12=12 2(7)+5=19 14+5=19 19=19

OpenStudy (anonymous):

#9 90+39=129 180-129=51 M<1=39 M<3=51

OpenStudy (anonymous):

#8 46+125=171 171/2=85.5

OpenStudy (anonymous):

#7 180-36=144 180-113=67 A=144 B=67

OpenStudy (anonymous):

#6 6x+16=49 6x=33 x=5.5

OpenStudy (anonymous):

#5 18x=90 x=5 5+y=90 y=85 30z=90 z=3

OpenStudy (anonymous):

There you go, that is the whole quiz.
