We know that
If two secant segments are drawn to a <span>circle </span><span>from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
</span>
so
BC*AC=CD*(x+CD)
AB=19
BC=10
CD=5
AC=AB+BC----> AC=29
(x+CD)=BC*AC/CD-----> 10*29/5-----> 58
(x+CD)=58------> x=58-CD-----> x=58-5----> x=53
Answer:
c = 2
Step-by-step explanation:
From the statement we have that If 14 is 7 times a number c, we can write the following equation:
7c = 14. Solving for c, we have:
c = 14/7 = 2
Answer:
answer: c
Step-by-step explanation:
C is the answer because 35 × 2 = 70 and sense this is a complementary angle it will add up to 90 degrees and 70 + 20 = 90 Hope that helps/explains well!
Answer:
Angle 1: 55 degrees
Angle 2: 55 degrees
Angle 3: 70 degrees
Step-by-step explanation:
<u>Finding angle 1:</u> We know that in a triangle, all three angles must add up to 180 degrees. In the triangle on the left, 2 of the angle measures are already given to us. Therefore, we can simply do 180 - 40 - 85, thus the measure of angle 1 is 55 degrees.
<u>Finding angle 2:</u> We know that opposite angles are congruent. Therefore, angle 2 and angle 1 have the same measure.
<u>Finding angle 3:</u> Using the same thought process as we used when finding the measure of angle 1, we can subtract the other 2 angles. 180 - 55 - 55 is equal to 70.
Answer:
y=-3x+4
Step-by-step explanation:
y-y1=m(x-x1)
y-4=-3(x-0)
y-4=-3(x)
y-4=-3x
y=-3x+4
