Answer:
<M = 78°
Step-by-step explanation:
The sum of angles in a kite is 360°.
One of the properties of a kite is that one pair of opposite angles are equal.
Since it is not <L and <N, it must be <O and <M
Therefore:
<O = <M = x
=> x + x + 130 + 74 = 360
2x + 204 = 360
2x = 360 - 204
2x = 156
x = 156/2 = 78°
This means that <M = 78°
Answer:
ans = 4
Step-by-step explanation:
he has 2 1\2 and 4 1\4
to find the ans, we must firstly find out his total amount of fabric, so we add the available fabric
first we add whole numbers
2 + 4 = 6
then we add fractions
1 1
--- + ---
2 4
2 + 1 3
------------- = ---
4 4
after we add the whole no and fraction
6 + 3\4 = 6 3\4
note 10 1\2 is greater than 6 3\4
so to find the part left, we
have
10 1\2 - 6 3\4
as our answer
Answer should be 36.95 if 1.4 is the radius
