Answer:
Step-by-step explanation:
If AB is tangent to the circle, then angle ABO is right angle and triangle AOB is special 
triangle. In this triangle, the leg that is opposite to the angle of 30° is half of the hypotenuse. Thus,
By the Pythagorean theorem,
Answer:
Step-by-step explanation:
12 inches is in a foot
10 x 7= 70
2 x 7= 14
70+14=84
Answer:
HL (Hypotenuse Leg)
Step-by-step explanation:
You have BC=CD (Because of reflexive property), AC=DC, and measure of BAC is equal to the measure of BDC, which is 90 degrees. Since these triangles are right and they have a hypotenuse and a leg congruent, you can say that they are congruent because of HL.
Answer:
Answer: 3 1/2 as a decimal is 3.5.
Step-by-step explanation:
B) y = -2x
when x = a
y = -2a
when x= 2a
y = -2(2a) = -4a
