Whereas the basic formula for the area shape is length x width the basic formula for volume is length x width c height
Answer:
x=104°
Step-by-step explanation:
180=(x+4) +72
180-72=x+4
108=x+4
108-4=x
104=x
x=104°
Hope this helps! :)
Answer:
Angle A is 77°
x = 3
AC = 13
Step-by-step explanation:
Angles A, B and C MUST add up to 180°. If Angle C is 26°, then the sum of A and B and 26° = 180°. In other words, A+B = 180° - 26° = 154.
Since A and B are equal, A = B = 154°/2 = 77°
Since this triangle is isosceles, sides AC and BC are equal. Thus,
7x - 8 = 3x + 4, or
4x = 12. Then x = 3.
Since AC = 7x - 8, and x = 3, AC = 7(3) - 8 = 21 - 8 = 13
Answer: 
Step-by-step explanation:
1) Reorder the terms: 
2) Solving: 
3) Add -34 to each side of the equation: 
4) Combine like terms: 34 + -34 = 0: 
5) Combine like terms: 47 + -34 = 13: 
6) Divide each side by -10:
