An isosceles triangle is a triangle that has 2 equal sides and 2 equal angles.
side XY = side XZ
∠Y = ∠Z
Since ∠Y = a° then ∠Z = a°
Because interior angles of a triangle sum up to 180°, we simply need to find the difference between 180° and the 2 known angles to solve for the measure of angle X.
∠X = 180° - 2a°
X= -5
Hopefully this helped :))
That’s not 25 points but ok
According to Another brainly user, this is the answer
(-1)^2.x+3= -x+7
x+3= -x+7
2x=4
x=2
Hope it helps!!!
Answer:
It will take 10 hours.
Step-by-step explanation:
By using the formula of motion,
v = u + at
Here, v = Final speed of an object
u = initial speed
a = Acceleration by which the speed is increasing
t = Duration or time
Now substitute the values given in the question,
80 = 50 + 3t
3t = 30
t = 10 hours
Therefore, after 10 hours speed of the bus will be 80 mph.
