Answer:
t = -14
Step-by-step explanation:×
I did 4+3 which equals 7.
Now I know I need t/-2 to equal 7.
Next, I did 7×2 which equals 14.
When you divide 2 negative numbers you get a positive number.
So -14 ÷ -2 = 7
So t = -14
Answer:
105
Step-by-step explanation:
Let the angle of B be x
According to the question,
5x+x=90
or, 6x=90
or, x=15
The angle of B is 15
The angle of A is (15*5)=75
The supplementary angle of A is
(180-75)=105

Answer:
The diameter of the circle is 9.
Step-by-step explanation:
Because circumference is equal to
* d, we can backtrack and use this equation to find diameter. Let's say
is equal to 3.14.
28.26 = 3.14d
Divide both sides by 3.14.
9 = d
The diameter of the circle is 9.
