Answer:
28
Step-by-step explanation:
-4+-7=28 you just reverse the division problem

Actually Welcome to the Concept of the Congruency of triangles,
since here, two sides with a in between angle is congruent, we will use the SAS congruency,
=> Side-Angle-Side congruency .
SAS.
Answer:
Its a i just took the test
Step-by-step explanation:
Answer:
all work is shown and pictured
The applicable theorem is the one that tells you the exterior angle is equal to the sum of the opposite interior angles.
9x = (5x) +(9 +x)
9x = 6x +9 . . . . . . . . collect terms
3x = 9 . . . . . . . . . . . . subtract 6x
x = 3 . . . . . . . . . . . . . divide by 3
The value of x is 3.
_____
The angles (clockwise from left) are then
(9*3)° = 27°
(5*3)° = 15°
(9 +3)° = 12°
This is an obtuse triangle, obviously not drawn to scale.
