Given the figure in the attached image.
Circle O has diameter FG and chord FH.
If arc GH is;

we want to find the measure of angle HFG.
Recall that from circle geometry theorems;
"The angle at the center of a circle is twice the angle at the circumference of the circle."
So;

substituting the value of GH;
Answer:
Step-by-step explanation:
Given : Expression 
To find : Solve the expression ?
Solution :
Step 1 - Write the expression,

Step 2 - Apply distributive, 
Here, a=25.36, b=1, c=0.45

Step 3 - Solve the expression,


Therefore, 
Answer:
Equation: 
x = -10 or x = 7
x = 7 (width can't be negative)
x + 3 = 10
Step-by-step explanation:
Represent the width of the rectangle by x. "The length of a rectangle EXCEEDS the width by 3" means the length is 3 LONGER than the width, so the length is represented by the expression x + 3.
Area = (length)(width)
70 = (x + 3)x
Multiply out the right side.

Factor the left side.

Each binomial could equal 0, so

The negative solution does not make sense as the width of a rectangle.
x = 7, making the length, x + 3 = 10
-0.01234567901 is your answer
