Answer:
B. ZJ = 85
C. KH = 68
Step-by-step explanation:
Given that ZK, ZL, ZM are perpendicular bisectors of ∆GHJ, they form a circumcenter which is equidistant from the vertices of ∆GHJ. According to the circumcenter theorem, ZH = ZG = ZJ = 85.
Also each median formed is equal. This means: KH = GH, LH = LJ, MG = MJ
Since HG = 136, KH = ½ of 136 = 68.
The two options that are true are:
B. ZJ = 85
C. KH = 68
Answer:
-5x+7-(3x-2)
=-5x+7-3x+2
=-8x+9
Step-by-step explanation:
Answer:
C = 13
Step-by-step explanation: According to the pythagorean theorem, which states A² + B² = C². This means that in this equation 5²+12²=x². When we solve this we get 169=x². Since 169 is the perfect square of 13 therefore the answer is 13.
Step-by-step explanation:
When x=-3, then
- (-3)²-5×(-3)-8
- 9+15-8
- 24-8
- 16
