answer : False
The measure of a tangent-tangent angle is one - half the difference of the measures of the intercepted arcs.
The diagram is attached below
AB and BC are the two tangents
By exterior angle theorem
∠3 = ∠2 + ∠4
So ∠2 = ∠3 - ∠4
Now we find angle 3 and 4, we know when a chord and tangent intersect at a point then the measure of angle is one half of measure of intercepted arc
∠3 = 
∠4 = 
∠2 = ∠3 - ∠4
∠2 = -
∠2 = 
The measure of a tangent-tangent angle is one half the difference of the measures of the intercepted arcs.
Answer: A. The distance traveled at 65 miles per hour for a certain amount of time.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Speed rate = distance/ time
Isolating distance:
Distance = speed rate x time
So, the time (T) multiplied by the speed rate (65) represents the distance traveled at 65 miles per hour for a certain amount of time.
In conclusion, the correct option is A.

Answer:
Question 12: 60°
Question 13: 30°
Question 14: 60°
Question 15: 120°
Step-by-step explanation:
Question 12: The measure of a circle is 360°, so ∠CGD which is 
of a full rotation is 60°.
Question 13: ∠CGH is 
of ∠CGD, so its angle measure is 30°.
Question 14: Since the interior sum of all angles in a triangle is 180° and two angles have measures of 90° and 30°, that means ∠HCG has a measure of 60°.
Question 15: Since ∠EGC is 
of a full rotation, and is twice as great as ∠CGD, that means it has an angle measure of 120°.
Answer:
x=-6
Step-by-step explanation:
5x-x-6=6(2x+7)
4x-6=<em>6(2x+7)</em>
4x-6=<em>12x+</em><em>42</em>
-8x=48 |:(-8)
x=-6
Answer:
x = 23
Step-by-step explanation:
Remember, angles in a triangle add up to equal 180
That being said we can create an equation to solve for x
180 = 110 + 35 + x + 12
now we solve for x
step 1: combine like terms
110 + 35 + 12 = 157
now we have 180 = 157 + x
step 2 subtract 157 from each side
180 - 157 = 23
157 - 157 cancels out
we're left with x = 23
