The 4th option would be correct.
{X | - Root 5 < x < Root 5 }
Answer:
C
Step-by-step explanation:
an exterior angle is supplementary to the adjacent interior angle.
So 180 - 55 = 125
180 - 65 = 115
The third angle of your triangle is 180 - 55 - 65 = 60
180 - 60 = 120
C is the only value that cannot be the measure of an exterior angle.
Answer:
15
Step-by-step explanation:
14^2 + 6^2 = H^2
196 + 36 = H^2
232 = H^2
*Square root both sides*
About 15 = H
Also: H means hypotheses
Answer:
x=4
Step-by-step explanation:
1) first write it down --> 11x-2+9x+1=19x+3
2) then combine like terms on the left side of the equation. --> 20x-1=19x+3
3) Then subract 19x on both sides --> x-1=3
4) After add 1 to both sides --> x=4
