Answer:
A
Step-by-step explanation:
The Tangent-Secant Exterior Angle Measure Theorem states that if a tangent and a secant or two tangents/secants intersect outside of a circle, then the measure of the angle formed by them is half of the difference of the measures of its intercepted arcs. Basically, what that means here is that 
equals half of the difference of 
and the measure of the unlabeled arc.
First, we need to find the measure of the unlabeled arc, since we can't find without it. We know that the measure of the full arc formed by the circle is 
, so the measure of the unlabeled arc must be 
by the Arc Addition Postulate.
Now, we can find . Using all of the information known, we can solve for like this:
Hope this helps!
Answer:
A, B, C
Step-by-step explanation:
The top right corner is the positive side of the graph. If it goes below the X axis or to left of the Y axis, it is negative. (thus, the negative numbers)
Centi- means "hundred". There are 100 centimeters in 1 meter.
2.8m•100cm=280cm
Answer:
Explanation: We need to find the area of the triangle, We know that the area of any right triangle is:
Therefore in the information given we have the following:
Therefore the Area of this triangle is as follows:
Note! Units are centimeter-squared
