Answer:
-3.5
Step-by-step explanation:
2x+21/2=x+7
2x + 10.5 = x + 7
-x -x
x + 10.5 = 7
-10.5 -10.5
x = -3.5
the sum of the interior angles is 180° (triangles)
it's isosceles, 2 equal sides and 2 equal angles.
you take away the given angle from 360° and you will find the sum of the 2 equal sides, you divide by 2 and you have the angle b (equal to angle C).
(180 - 72) : 2 =
108 : 2 = 54° (your answer)
-----------------------
72 + 54 + 54 = 180°
The answer is good.
Answer:
f(-14)=-15
Step-by-step explanation:
What ever is in the parentheses after the letter (in this case it's f) will be the x value since f(x).
So
f(-4)=5(-4)+5
Then solve.
f(-4)=-20+5
f(-4)=-15
-15
