Answer:
x = 8
y = 21
Step-by-step explanation:
(7x + 12)° and (12x - 28)° are alternate interior angles. Alternate interior angles are congruent. Therefore:
(7x + 12)° = (12x - 28)°
Solve for x
7x + 12 = 12x - 28
Collect like terms
7x - 12x = - 12 - 28
-5x = -40
Divide both sides by -5
-5x/-5 = -40/-5
x = 8
(12x - 28)° + (9y - 77)° = 180° (linear pair)
To find y, plug in the value for x = 8.
12(8) - 28 + 9y - 77 = 180
96 - 28 + 9y - 77 = 180
Combine like terms
- 9 + 9y = 180
Add 9 to both sides
-9 + 9y + 9 = 180 + 9
9y = 189
Divide both sides by 9
9y/9 = 189/9
y = 21
Bottom Side Surface Area:
(24 inches + 24 inches + 24 inches) * (30 inches)
= 72 inches * 30 inches
= 2160 inches squared
--------
Top Side Surface Area:
24 inches * 30 inches
= 720 inches squared
--------
Length of the diagonal (D) which needs to be measured:
*Use Pythaogras's theorem...
24^2 + 10^2 = D^2
D=√(24^2+10^2)
D=26 inches
------------
Measure the surface area of the two ramps:
26 inches * 30 inches * 2
= 1560 inches squared
-----------
Total surface area:
2160 inches squared + 720 inches squared + 1560 inches squared
= 4440 inches squared
---------
Answer:
4440 square inches
U just divide 70 and 45 and u get your answer
Do you need x as your answer or y
