Answer:
a) 13, 10, 16
Step-by-step explanation:
The usual form of the triangle inequality requires the sum of the two shortest sides exceed the longest side (a+b>c). The only choice for which this is true is ...
10 + 13 > 16 . . . . choice A

<em>Comment on the triangle inequality</em>
Some authors also allow the sum to equal the longest side (a+b≥c). In that case, choice B (1+2=3) is also an answer. This "triangle" would look like a line segment of length 3. It has zero area.

Answer:
x = 25
Step-by-step explanation:
This is an equilateral triangle as all 3 angles are marked as equal.
Hence the 3 sides are equal
Equate any 2 and solve for x
4x - 30 = 3x - 5 ( subtract 3x from both sides )
x - 30 = - 5 ( add 30 to both sides )
x = 25
As a check on the sides
4x - 30 = (4 × 25) - 30 = 100 - 30 = 70
3x - 5 = (3 × 25 ) - 5 = 75 - 5 = 70
2x + 20 = (2 × 25 ) + 20 = 50 + 20 = 70
confirming that x = 25
