What is the name of the angle formed by BA and BC', given that the two rays share a common endpoint?
1 answer:
Answer:
B. ∠ABC
Step-by-step explanation:
When naming an angle using three points, the points should be given in order, with the vertex of the angle in the middle. B is the only option that has the letters in the right order.
∠CBA would also be a valid name for the angle, but that's not one of the options.
The diagram below shows what the problem is describing.

Step-by-step explanation:
This is a linear equation in slope intercept form which is
where m is the slope and b is the y intercept.
The equation
Has a slope of -1/3 so this means that the slope will be decreasing. A negative linear equation increases as we go left. and decreases as we go right. The y intercept is 2. So this means the graph must pass through (0,2) and when x=0, y must be 2.
In other words, look for a line that the y values increase as we go left and decrease we go right. Also look for a point (0,2) and make sure the graph pass through it.
Answer:
36.5cm²
Step-by-step explanation:
Area of quarter circle=8²/4=64
/4=16
cm²
Area of square+Area of shaded region =2(16)=32
=100.5cm²
Area of square=8²=64cm²
Area of shaded region=100.5cm²-64cm²=36.5cm²
Therefore, the area of the shaded region is 36.5cm².
