I think it’s b! i hope that helps!
Answer:

Step-by-step explanation:
The picture shows three isosceles tirangles with the same legs. The base of each triangle is 12 units, 5x-3 units and 17 units.
Since the angles at vertex of each isosceles triangles are 27°, 28° and 29°, then the lengths of the bases satisfy the double inequality
15<5x-3<17
Add 3 to this inequality
15+3<5x-3+3<17+3
18<5x<20
Divide it by 5:

The second answer is correct because in order for the ordered pairs to represent a function, there can only be 1 y value for every x value. The second option has 2 different y values for x = 3 so it is not a function.
The answer is the second option.
Answer:
Acute, Equilateral
Step-by-step explanation:
Acute because all angles (which are 60 degrees) are less than 90 degrees.
Equilateral because all sides are equal.

Answer:
(mark me brainliest) q=5
Step-by-step explanation:
q would be = 5
and so would the height = 5
here is the rule for 45-90-45
hypotenuse is basically the other two lengths with 
so that is why q would be 5
