Answer:
\angle ACB=40^{\circ}, \angle ABC=63^{\circ}
Step-by-step explanation:
Finding x:
We know that
, because it's a straight line. So,
.
We know that the sum of the angles of any triangle will be
.
So, we have that
.
Combining like terms on the left gives
.
Subtracting
from both sides gives
.
Dividing both sides by
gives
.
Finding missing angle measures:
.
.
So,
and
and we're done!
Note:
. Coincidence? If not, try and prove it!
Answer:
- 28
Step-by-step explanation:
Determinant of matrix J is
- 2(5) - 3(6) = - 28
You are dividing the number with the x so 4 when you divide 4 on both sides 4x cancels out because it’s 0 and 8 divides by 4 is 4 so y=4
