Answers are:
A. 5,6,8
B 3,5,6
D 5,5,9
Answer:
yes
Step-by-step explanation:
Two congruent angle for diagram 8 would be angle LNV and angle PNM. Two congruent angles for diagram 9 would be angle BCE and angle FCD.
Answer:
8.5
Step-by-step explanation:
slope of the line that contains KL
(y2 - y1)/(x2-x1)
(0-1)/(7-3)
m = -1/4
slope of the line that contains JK
(5-1)/(4-3)
m = 4
the linea are perpendicular so triangle is right
area = (leg1 x leg2)/2
KL = 
KJ = 
area = (√17)^2/2 = 17/2 = 8.5

Step-by-step explanation:
<u>Step 1: Define</u>
-21 = z - (-6 - 2z)
<u>Step 2: Solve for </u><u><em>z</em></u>
- Distribute negative: -21 = z + 6 + 2z
- Combine like terms: -21 = 3z + 6
- Isolate <em>z</em> term: -27 = 3z
- Isolate <em>z</em>: -9 = z
- Rewrite: z = -9
