Answer:
<ABC = 15
< BAC = 150
Step-by-step explanation:
<C = <B since this is an isosceles triangle. We know this because AC = AB
<C = 15 so <ABC = 15
The sum of the angles of a triangle is 180
A + B+ C = 180
A + 15+15 = 180
A +30 =180
A = 180-30
A = 150
< BAC = 150

it is d because they dont have enuff info :)
Answer:
Distributive property.
Step-by-step explanation:
The 2 is being distributed to both the x and the 3.
Answer:
2
Step-by-step explanation:
x f(x)
−3 −1.5
−2 −1
−1 −0.5
0 0
1 0.5
2 1
3 1.5
This table shows the input and output values for a linear function f(x).
Now, two inputs which are four values apart are say -3 and 1 and the corresponding outputs are - 1.5 and 0.5.
Therefore, the positive difference of outputs is [0.5 - (- 1.5)] = 2 (Answer)
Answer:
C = 420/h + 400
Step-by-step explanation:
Let s be the side of the square base.
Let h be the height
Volume = s*h
20 = s*h
s = 20/h
Cost of glass is
5(20/h) + 5(4* h*20/h)
= 100/h + 400
Cost of frame is
2*4(20/h) + 2*4(20/h)
= 160/h + 160/h
= 320/h
Total cost = C
C = cost of glass + cost of frame
C = 100/h + 400 + 320/h
C = 420/h + 400
