Answer:
Use the "find vertically opposite angle" method.
a = 80°
To find the other angles:
Since the angles equal up to 360 which makes a full circle shape...
360 - 80 - 80 = 200 (B and C)
200 ÷ 2 = 100 (Angle for B and C since they are vertically opposite, hence having the same angle)
b = 100°
c = 100°
The first step I would do would be to list the factors of 28.
28(1)
14(2)
7(4)
Now notice that 7 + 4 = 11
So that means that -7 + -4 = -11.
Therefore, -7(-4) = 28
Your two numbers are - 7 and - 4. Hope that helps!

Step by Step Explanation:
- Evaluate the power: Any non-zero expression raised to the power of 0 equals 1
- Simplify: Simplify the expression
- Calculate the product: Any expression multiplied by 1 remains the same.

If we say that side "a" is the shortest (adjacent), side "b" is the second shortest (opposite), and side "c" is the longest (hypotenuse): then angle A would be 30°, angle B would be 60°, and angle C would be 90°
tan B = b/a
or
a tan B = b
they have 4 as the smallest value in all four options, so we know that
a=44 tan 60° = b
tan 60° = √3
so, 4 tan 60° = 4√3
b=4√3that leaves two options left, so now we find "c":
c^2 = (a^2) + (b^2)
OR



so
a=4, b=4√3, and c=8
