Answer:
1 = 35
2 = 55
Step-by-step explanation:
so we know that between 1 and 2 it is 90 degrees we also know that angle 1 and the angel to the left of it make 180 degrees so do
180 - 90 = 90
this means the angle next to line 1 is also 90 degrees
then we would see that the 55 degrees the 90 degrees and angle 1 make 180 degrees so do
55 + 90 = 145
180 - 145 = 35 degrees so angle 1 is 35 degrees
then we would find angle 2
90 - 35 = 55 degrees so angle 2 = 55
hope this helps : )

Answer:

Step-by-step explanation:
The calculator approximated the value of y at 7.8.
We need to complete the error interval for y.
In other words, we calculate the upper and lower bound for y.
The level level of accuracy is to the nearest tenth.
To find the lower bound, we subtract half the degree of accuracy to get:

To find the upper bound, add half the level of accuracy to get:

Therefore the error interval is

We know that
circumference=2*pi*r
for r=65/2----> r=32.5 cm
circumference=2*pi*32.5-----> 204.1 cm
so
one revolution <span>of Emma’s bicycle</span> is equal to 204.1 cm-----> 2.041 m
3.2 km-------> 3200 m
1 revolution---------> 2.041 m
x rev------------> 3200 m
x=3200/2.041 ----> x=1567.86 revolutions
the answer is
1567 complete revolutions
-5 is the intercept since y=mx+b, b being the intercept.
