Pythagoras Theorem:
hipotenuse²=side1² +side2²
a=is the longest side of the triangle (hypotenuse)
b and c: are the other two sides.
In this case:
hipotenuse²=side₁² + side₂²
side₁=a=16
side₂=b=28
c²=16²+28²
c²=256+784
c²=1040
c=√1040=32.2490....≈32.25
Answer: D. 32.25
The value of a is (c) 86
<h3>How to solve for a?</h3>
The given parameter is:
Angle C = 86
By vertical angle theorem, we have:
Angle A = Angle C = 86
This implies that:
Angle A = 86
The arc A subtends angle A
This means that:
Arc A = 86
Hence, the value of a is (c) 86

I don't think this is possible...
But if you mean 9 then the root is 3
I'm going to use the substitution method.
If y = - 3/2 - 7, then:
1/2x + 5 = - 3/2x - 7
Combine like terms:
4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)
Simplify to get:
x = - 6.
Plug - 6 back in for x in either equation.
Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.
X = - 6, Y = 2
Answer:
C.(6, 4,2)
since every element of B is also an even number,so is an element of C
