Chloe this is your math teacher, stop cheating
B is the most misleading because the amount of miles decreases. This would mean that the racer would have gone forward, then backward, then forward again.
Answer:
a. 26 units²
Step-by-step explanation:
The x-axis conveniently divides the figure into a triangle (above the x-axis) and a trapezoid (below the x-axis).
The top triangle has a base of 4 and a height of 3, so its area is ...
triangle area = (1/2)(4 units)(3 units) = 6 units²
The bottom trapezoid has a top base of 4, a bottom base of 6, and a height of 4 units. Its area is ...
trapezoid area = (1/2)(b1 +b2)h = (1/2)(4 units + 6 units)(4 units) = 20 units²
The total area of the figure is ...
area = triangle area + trapezoid area = 6 units² + 20 units² = 26 units²
The intercepted arc is twice the size of the inscribed angle. For instance, here we have the inscribed angle with 50° so x(intercepted arc) = 2*50 = 100°
The other example is the intercepted arc given and inscribed angle needed. So divide 40° by 2 we will get 20°. So y = 20°
x = 100°
y = 20°
Hope it helps :)
