The third is because the prove is x = fifteen and if a number is next to a letter, it means multiply, sorry I could only do one.
Answer:
The value of the exterior angle is
Step-by-step explanation:
we know that
The sum of the interior angle plus the exterior angle is equal to , because are supplementary angles.
Let
x-----> the measure of the exterior angle
so
solve for x
Answer:
y-intercept = 4
x-intercept = 2
Step-by-step explanation:
you can divide the equation through by 4 and change into the y=mx+c form to find c, the y intercept so the y-intercept = 4.
for the x intercept make the y=0 (because the coordinate point where the line crosses the x axis must have y=0) and then you get 8x=16 so x=2
Answer:
Geometric Mean = 9.17
Step-by-step explanation:
Here,
a = 7
b = 12
Geometric mean = root(ab)
= root( 7 x 12)
= root(84)
= 9.17
