All three angles of a triangle must equal 180 degrees, so you’d add the measures of angles BAC and ABC, which equals 86. Then you’d subtract 86 from 180 because you only have one angle left. So, your answer should be 94. Hope this helps!
Answer:
P(- 4, - 8 )
Step-by-step explanation:
The abscissa is the x- coordinate and the ordinate is the y- coordinate.
Here b = 2a , thus
a + 2a = - 12
3a = - 12 ( divide both sides by 3 )
a = - 4
and b = 2a = 2 × - 4 = - 8
P(- 4, - 8 )
Answer:
Does exist -- It only exists when the determinant does not equal zero.
Step-by-step explanation:
The inverse of a matrix is the transpose of the cofactor matrix, divided by the determinant. If the determinant is zero, the result of the division is undefined and the inverse does not exist.
__
For this matrix, the determinant is (-2)(18) -(9)(4) = -72. The inverse exists.
