Answer:
No, a triangle could not have these side lengths.
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. Let's say side a = 1.2, b = 1.9, and c = 3.1, if we add a+b, then the sums are equal to side c. This would not satisfy the Triangle Inequality Theorem because one configuration of the equation results in the sum and third length being congruent, rather than greater.
Answer:427.2
Step-by-step explanation:
8.9 13.6 18.3
it goes up in 4.7
4.7n
8.9-4.7=4.2
4.7n+4.2
4.7(90)+4.2
423+4.2=427.2
Hopefully it is correct :)
Answer:
B. 2
Step-by-step explanation:
Based on the Midsegment of a trapezoid theorem:
GH = (BC + FE)/2
9x - 3 = (19 + (5x + 1))/2) (substitution)
9x - 3 = (20 + 5x)/2
Cross multiply
2(9x - 3) = 20 + 5x
18x - 6 = 20 + 5x
Collect like terms
18x - 5x = 20 + 6
13x = 26
Divide both sides by 13
x = 26/13
x = 2
The area of a triangle is
(4.5feet)(5.75feet) and that would equal 12.9375 feet²
