Answer:
24 cm
Step-by-step explanation:
The triangle must have the ratio of 6:7:9 for side lengths. If the triangle had these exact sides then the perimeter would be 6 + 7 + 9 = 22 cm. Since the triangle has 88 cm as its perimeter then 22*4 = 88. This means multiplying by a scale factor of 4 will give the side length.
6 * 4 = 24
7* 4 = 28
9 * 4 = 36
The perimeter is 24 + 28 + 36 = 88 cm.
The shortest side is 24.
Answer:
Step-by-step explanation:
Angles a and b are opposite, so they are equal. The same is true for angles O and 3b.
So, the four angles are actually (starting from the left and going clockwise) 3b,b,3b,b
These four angles sum up to 360, so we have
And since a and b were the same, a is also 45 degrees.
Answer: (3, 6)
Step-by-step explanation:
3x + y = 15
y = 2x
Using substitution:
3x + 2x = 15
5x = 15
x = 15/5
x = 3
y = 2x
y = 2 * 3
y = 6
x = 3
y = 6
= (3, 6)
Answer:
D is your answer.
Step-by-step explanation:
Surface area is equal to all faces on the prism.
If you simplify it:
(5)(12) + (5)(10) + (12)(10) + (13)(10)
SA = 360 cm^2
