Answer:
Step-by-step explanation:
salut :
en utilisant le theorem de Pythagore on obtient :
AC²= AB² + BC²
(a+5)² = 7²+a²
a²+10a+25 = 49+a²
10a+25 =49
10a =24
donc : a = 24/10 = 12/5 = 2.4 unit
The distance travelled by the car will be 3.6km in 2 minutes.
<u>Explanation:</u>
Given:
Speed, s = 108 km/hr
s in km/min = ?
1 hr = 60 min
So,
108 km/hr = 
= 1.8 km/min
time, t = 2 min
Distance, d = ?
We know:
distance = speed X time

Therefore, the distance travelled by the car will be 3.6km in 2 minutes.

Answer:
x = 58°
Step-by-step explanation:
Length of tangents drawn to a circle from a point outside the circle, are equal in measure.
By using this property,
Two tangents PQ and PR will be equal.
And angles opposite to these sides will be equal.
Therefore, ∠PQR ≅ ∠PRQ
By triangle sum theorem,
m∠PQR + m∠PRQ + m∠QPR = 180°
x° + x° + 64° = 180°
2x = 180 - 64
2x = 116
x = 58°
