Can someone pls help me on 17 and 18 thank u
NemiM [27]

Answer:

17. 48

18. 15

Step-by-step explanation:

The properties of a rhombus is such that all angles are equal to each other as well as the lengths, so all the lengths will be the same. Therefore we can use that fact to equate KL and LU.

17. 4x - 3 = 3x + 9

x  = 12

LU = KC

3(12) + 9 = 36 + 9 = 48 Here, we substitute the x value we worked out into this expression to find out the length of KC.

KC = 48

18. LYU is a right angle so it is 90 degrees

5x + 15 = 90

5x = 75

x = 15
