Answer:
the answer is 85° because all angles in a triangle add up to 180
so u add them both up, subtract from 180 n u get 85
Jeff is correct because:
2 sides of a triangle must always be longer than the other side, so:
12+8>19
19+8>12
12+19>8
Since all of them are true, Jeff is correct
Answer:
y= (x+4)(x+4) is the answer
Step-by-step explanation:
Identity used= (a+b)²= a²+2ab+b²
∠KMN = (1/2)*arc KN . . . . . . this relationship is true of any inscribed angle. (It is a useful relationship to remember.)
= 95°/2
= 47.5°
