Answer:
12 ft² :)
Step-by-step explanation:
Area of a parallelogram = base * height
4 * 3 = 12
Area of the parallelogram = 12 ft²
Answer:
X = 9
92 + 34 + 54 = 180 degrees
Step-by-step explanation:
180-14x + 92 + 3x + 7 = 180
-11x + 99 = 180 - 180
99 = 11x
X = 9
Answer:
c) 4x = 20
x = 5
Step-by-step explanation:
Let the number of people in a van = x
Number of people in 4 vans = 4 *x = 4x
4x = 20
Divide both sides by 4
x = 20/4
x = 5
Answer:
y = 8
Step-by-step explanation:
11y + 4y + 60 = 180
11y + 4y = 120
15y = 120
y = 8
Answer:
6.63 cm
Step-by-step explanation:
The segments within the circle form a right angle. Triangle CRS as a right triangle must follow the Pythagorean theorem which says the square of each leg adds to the square of the hypotenuse.
a² + b² = c²
Here a is unknown, b = 10 and c = 12.
a² + 10² = 12²
a² + 100 = 144
a² = 44
a = √44 = 6.63
