Answer:
The value of 
The value of 
Step-by-step explanation:
Generally the total angle that make up a circle is
From the diagram we see that
=> 
Generally angle that is formed as a result of interception of a chord and a tangent is equal to the intercepted arc divided by 2
This implies that
substituting values
Answer:
The slope of a line that has a y-intercept but no x-intercept will be zero.
Step-by-step explanation:
If the line has no x-intercept, then it never intersects the x-axis, so it must be parallel to the x-axis.
If a line does not have an x-intercept, it means it would never intersect the x-axis.
Thus, it must be parallel to the x-axis, meaning its slope will be zero. It would be just a horizontal line.
For example, y=9 is the line equation that does not have an x-intercept and its slope is zero.
Therefore, the slope of a line that has a y-intercept but no x-intercept will be zero.
9x(6+x)
54x+9x
43x
So in the end the answer after doing the work it will be 43x
Answer:
34
Step-by-step explanation:
(3 + 5i)(3 - 5i) = 9 - 25i^2
because i^2 = -1 9 - 25i^2 = 9 - 25x-1 = 34
hope this helped
The opooste angles are equal
so
4y-8=79+y
minus y both sides
3y-8=79
add 8 both sides
3y=87
diide both sides by 3
y=29
