Step-by-step explanation:
1
4x = 3x + 5 ( subtract 3x from both sides )
x = 5
2
7m = 8 + 5m ( subtract 5m from both sides )
2m = 8 ( divide both sides by 2 )
m = 4
3
2a = 9 - a ( add a to both sides )
3a = 9 ( divide both sides by 3 )
a = 3
4
d = 3 ( multiply both sides by 4 to clear the fraction )
d = 3 × 4 = 12
5
5y + 6 = 21 ( subtract 6 from both sides )
5y = 15 ( divide both sides by 5 )
y = 3
6
2n - 3 = 6 ( add 3 to both sides )
2n = 9 ( divide both sides by 2 )
n = 4.5
A is the answer i hope this heps
Answer:
x = 135°
Step-by-step explanation:
4 sides and the diagonal are the same.
Therefore, it is square with each interior angle = 90°
The diagonal bisects the interior angle to 45° , 45°
x + 45° = 180° [ straight line angle ]
x = 180 - 45 = 135°
We know that
if <span>points a and b lie on the circle and O is the center
so
OA is the radius
OA=OB
5x-11=4(x-1)-----> 5x-11=4x-4----> 5x-4x=11-4-----> x=7
OA=5x-11-------> OA=5*7-11-----> OA=24 units
the diameter is (OA+OB)
2*OA------> 2*24------> 48 units</span>
