Answer:
4 with 3
Step-by-step explanation:
the only ones that are perpendicular to each other are
y = 7/4 x - 2 with y = - 4/7 + 2
since the condition is met so that two lines are perpendicular
slope1 * slope2 = -1
7/4 * -4/7 = -1 correct
Answer:
Step-by-step explanation:
First, we calculate the unknown angle of the left triangle and right triangle:
Unknown angle for left triangle⬆️
Unknown angle for right triangle⬆️
Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:
The angle 65° and angle of x are vertical angle.(both are equal)
So... <u>x= 65°</u>

We know that
circumference=2*pi*r
for r=3 in
circumference=2*pi*3------> 18.84 in
if 2*pi radians (full circle) has a length of--------> 18.84 in
7*pi/3 radians-----------------> x
x=7*pi/3*18.84/(2*pi)-------> x=21.98 in
the answer is
21.98 in
