Answer:
-2+5x+2x-4
Step-by-step explanation:
Answer:
x=2*sqrt(5)
Step-by-step explanation:
Since the triangle is isosceles, the other side of the triangle is sqrt(10) too. By using Pythagoras theorem, we have 10+10=x^2, x=2*sqrt(5).
You can solve for sides of a triangle using the following equation.
A = arccos (b^2 + c^2 - a^2/2bc)
And likewise for other variables by moving the letters.
Ultimately, in this problem you get the following angle measures:
15.87
23.97
140.16
Answer:
6 hours and 15 minutes
Step-by-step explanation:
4 hours + 45 minutes + 1 hour + 30 minutes = 5 hours + 75 minutes = 6 hours + 15 minutes
Answer:
78.5 ft²
Step-by-step explanation:
The area of a circle is given by
Area = πr²
where r is the radius = given as 5 ft
π = 3.14
substituting the values into the equation, we get
Area
= πr²
= (3.14) (5²)
= 78.5 ft²
