Answer:
5
Step-by-step explanation:
It's a right triangle so 7x + 11x = 90
Solve for x
7x + 11x = 90
18x = 90
x = 5
Exact Form:
x=√7, −√7
Decimal Form:
x=2.64575131… ,−2.64575131…

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°
