Answer:
<h3>12 hours</h3>
Step-by-step explanation:
Distance = 300 km
Speed = 25 km/h
Time = ?
Substitute values into the given equation
The measure of the unknown angles in the kite are as follows;
- x = 66 degrees
- y = 158 degrees
<h3>How to find the measure of a kite?</h3>
A kite has two pairs of adjacent equal sides.
In other words, a kite is a quadrilateral that has 2 pairs of equal-length sides and these sides are adjacent to each other.
One pair of opposite angles is equal. Diagonals are perpendicular to each other.
A kite has four interior angles and the sum of these interior angles is 360°
Therefore, the measures of the
x = 66 degrees.
Let's find y.
y = 360 - 70 - 66 - 66
y = 158 degrees.

Answer:
(-3, 5)
Step-by-step explanation:
X + y = 2---------------1
X - y = 8----------------2
Substitution method
X = 8 + y
Put x = 8+ y in 1 above
(8+y) +y= 2
2-8= 2y
-6 = 2y
Y= -3
Do same for x
