Which statement about BC←→ is correct?

Mathematics
1 answer:
KIM [24]3 years ago
3 0
Hello!

So a tangent line is perpendicular to the radius, which means it creates a 90 degree angle with the radius of the circle. The sum of the interior angles of any triangle is 180 degrees. To determine if line BC is a tangent line, we have to determine if angle ABC is 90 degrees. Well we know the degrees of the other two angles of the triangle, so let's set up an equation:

180 = 48 + 47 + x
180 = 95 + x
85 = x

Since angle ABC must be 85 degrees (not 90), line BC is not a tangent line.

Answer:
<span>BC←→ is not a tangent line because m∠ABC ≠ 90°.</span>

1. a= 60 (vertically opposite angles)

b= 360-(60+60)=240/2= 120 (angles at a point)

c= 120 (vertically opposite angles with b)

2. c= 90-40= 50 (vertically opposite angles)

b=a=360-90-90=180/2=90 (angles at a point)

3. a= 180-52-51= 77 (angles on a straight line)

b=52 (angles at a point)

d=51 (angles at a point)

c=77 (angles at a point)

4. a= 60 (vertically opposite angles)

b= 360-(60+60)=240/2= 120 (angles at a point)

c= 120 (vertically opposite angles with b)

e=65

d=f= 360-65-65=230/2=115

h=55

i=g=360-55-55=250/2=125

5. b=163

a=90

e=70

d=360-70-70=220/2=110

c=360-163-163=34/2=17

Hope this helps!

Help pls! Complex numbers :sin(2+3i).......Function Values Compute ( in the form u + iv).?
hjlf
<span>sin(a+bi) = sina·coshb + i·cosa·sinh<span>b
sin(2+3i) = sin2·cosh3 + i·cos2·sinh3
so
u = sin2cosh3
v = cos2sinh3

Amir stands on a balcony and throws a ball to his dog, who is at ground level.
ludmilkaskok [199]

Answer:

6 seconds

Step-by-step explanation:

h(x)=-(x-2)^2+16

We want h(x) to be 0 ( that is when the ball hits the ground)

0 = -(x-2)^2+16

Subtract 16 from each side

-16  = -(x-2)^2+16-16

-16 = -(x-2)^2

Divide by -1

16 = (x-2)^2

Take the square root of each side

sqrt(16) = sqrt((x-2)^2)

±4 = x-2

Add 2 to each side

2±4 = x-2+2

2±4 =x

2+4 = x   2-4 = x

6 =x  -2 =x

Time cannot be negative so x=6

Under her cell phone plan, Sydney pays a flat cost of $35.50 per month and
Keith_Richards [23]

The number of gigabytes that Sydney can use while staying within her budget is less than 2.9 gigabytes.

<h3>What are gigabytes?</h3>

gigabytes (GB) – pronounced with two hard Gs – is a unit of storage capacity equal to approximately 1 billion bytes. In decimal form (base 10), a gigabyte is exactly one billion bytes. In binary form, a gigabyte is 230 bytes or 1,073,71,82 bytes. Giga comes from the Greek word for giant. Werner Buchholz is credited with coining the term byte in 1956 and helped design IBM's 7030 Stretch, the first transistorized supercomputer.

gigabytes has been a common unit of measurement for data storage products since the mid-1980s. In recent years, terabytes (TB) have become a more common measure of storage capacity, especially for hard drives and solid-state drives.
