In a rhombus all sides are congruent, and opposite angles are congruent.

OpenStudy (anonymous):

Okay im confused on sloving In the rhombus m∠1 = 18x, m∠2 = x + y, and m∠3 = 30z. Find the value of each variable. The diagram is not drawn to scale.

OpenStudy (anonymous):

then for the second one i don't get In the rhombus m∠1 = 106. What are m∠2 and m∠3? The diagram is not drawn to scale.

OpenStudy (mathstudent55):

The diagonals are perpendiculars, so they intersect at right angles.

OpenStudy (mathstudent55):

Angles 1, 2, 3, and the other one with no number are all 90-degree angles.

OpenStudy (anonymous):

so there all 90 degree angles. m∠1 = 18x, m∠2 = x + y, and m∠3 = 30z. im suppose tofind x,y and z.

OpenStudy (mathstudent55):

You are given m<1 = 18x, but you also know that m<1 = 90, so you can solve for x.

OpenStudy (mathstudent55):

18x = 90 Now solve for x

OpenStudy (anonymous):

x=5 ?

OpenStudy (mathstudent55):

yes

OpenStudy (anonymous):

how do i find y and z from that?

OpenStudy (mathstudent55):

Now look at m<2 = x + y. You know m<2 = 90, and x = 5. Plug in and solve for y

OpenStudy (anonymous):

5+y? or 5+ 90?

OpenStudy (anonymous):

answer choice is one of these x = 5; y = 175; z = 6 x = 5; y = 85; z = 3

OpenStudy (anonymous):

i know x= 5
