Answer:
Either
or 
Step-by-step explanation:
Given that : one angle is
greater than another. Let the two angles be represented by a and b. Since one angle is
greater than another, then:
b = a + 
But;
a + b =
(sum of angles on a straight line)
a + a +
= 
2a =
- 
a = 
b =
+
= 
Therefore the measures of all angles formed by the lines is either
or
.
Answer:
second one i think
Step-by-step explanation:
We have been given a circle H, in which length of arc XY is 78 miles and measure of arc XY is 70 degrees. We are asked to find the radius of circle.
We will use arc length formula to solve our given problem.
, where,
r = Radius of circle,
= Central angle corresponding to arc.
We know that the measure of central angle that corresponds to arc XY will be equal to measure of arc XY.







Upon rounding to nearest hundredth, we will get:

Therefore, the radius of circle H is approximately 63.88 miles.
P/L=4/7 and P=L-12 so
(L-12)/L=4/7 multiply both sides by 7
(7L-84)/L=4 multiply both sides by L
7L-84=4L subtract 4L from both sides
3L-84=0 add 84 to both sides
3L=84 divide both sides by 3
L=28, and since P=L-12
P=16
So they had 28+16 = £44 in total.
The circumference is usually three times as much as the diameter
