Answer:
2 < c < 12
Step-by-step explanation:
Let the last side of the triangle = c
The sum of any two sides must be greater than the third side. Let's say we have triangle ABC, where a = 5 inches and b = 7 inches
a + b > c (1)
a + c > b (2)
b + c > a (3)
From (1);
a + b > c
7 + 5 > c
c < 12
From (2):
a + c > b
7 + c > 5
7 - 5 < c
c > 2
From (3):
b + c > a
5 + c > 7
c > 7 - 5
c > 2
So the possible lengths of c are: 2 < c < 12
To solve, isolate the variable (x)
Steps:
a) simplify 4/6, the smaller the number the better when it comes to fractions:
2/3x - 34 =32
b) add 34 to both sides:
2/3x = 66
c) multiply by 3 to get it out of the denominator:
2x = 198
d) divide by 2 to isolate x:
x = 99
Answer:
124
Step-by-step explanation:
A triangle is BH/2
6.2 is the height and 5 is the base
one triangle is 15.5 so multiply it by 8 since its an octagon
