Answer:
x = 44°
Step-by-step explanation:
Since this is an isosceles triangle, the other angle that isn't defined is also 68°. So, since all the angles add up to 180°,
x + 68(2) = 180
x + 136 = 180
x = 44°
Answer:
x=80
Step-by-step explanation:
Step-by-step explanation:
4x+5y=4 (equation 1)
2x-y=9 (equation2)
solving equation 1 and 2 and multiplying equation 2 by 2
4x+5y=4
4x-2y=18
- + -
________
7y= -14
y= -2
putting the value of y in equation 2
2x-y=9
2x+2=9
2x=7
x=3.5
For U= (2,3,4,5,6,7,8), X=(2,3,4,5), state X'=
tatiyna
Answer:
X' = {6,7,8}
Step-by-step explanation:
X' is the set that contains the elements that are in set U bot NOT in set X.
Answer:
Step-by-step explanation:
We are given that c=6 units
We have to find the side length a and b.
We know that sum of angles of a triangle =180 degrees
Substitute the values then we get
sine law:
