Answer:
Let the adjacent angles of the rhombus be 2x and 3x. We know that the sum of the measures of the adjacent angles is equal to 180°. AD = DC = 3 × 36° = 108°. Hence , the angles of the rhombus are 72° , 108° , 72° and 108°.
Step-by-step explanation:
Add them up and divide by 180
Yes, you are correct to use proportions because they are similar triangles.
Answer:
The answer is pretty obvious and it's 3/4
Step-by-step explanation:
Unless their is some other information, this answer is correct
Answer:
-27/5
Step-by-step explanation:
[x*4 + 3(x-1)]\12=2+x
4x+ 3x -3 =12(2+x)
7x -3 =24 +12x
7x-12x =24 +3
-5x =27
x = (-27/5)
