Step-by-step explanation:
the second equation should be multiplied by 9
A) the angle is 105 because its supplemental with the 75 degree angle
B) the angle's 75 because the given 75 degree angle is correspondant
C) 105 again because they are supplemental
The are of the triangle will be 12.5 units.
On marking the given vertices (0,0), (0,5), (5,5) of the triangle we get, the base of the triangle = 5 units and height of the triangle = 5 units.
Now, we know area of triangle =
Y=mx+b
y=80x+25
for every hour you must pay 80$
how many hours is X
and B is the rate you must pay anyway for the lesson and how many hours you have rented.
