RZ= RZ over 4 -2
SW= SW over 9 + 11 over 9
Answer:
15
Step-by-step explanation:
the diagonal of a rhombus are perpendicular, so we can use the Pythagorean theorem to solve this problem:
CL = √17^2 - 8^2 = √289 - 64 = √225 = 15
The answer is 15.65.
I solve it below, to find the answer you only need to use the distance formula.
Hello,
The 3th angle of the triangle is the supplement of 3x-8:
180-(3x-8)=180-3x+8=188-3x
The sum of all angles of the triangle is 180
180=2x+21+188-3x
==>180=-x+21+188
==>x=21+188-180
==>x=21+8
==>x=29
