What’s #10 I need it worked out not just the - 1

Answer 1
Answer: No, you can clearly see that angle4 is an obtuse angle while angle2 is more of a right angle. Since 3 and 5 are vertical angles means that 180-angle3=angle4 BUT 180-angle3=angle2 AND angle 1. So they are not vertical angles.

Vertical angles are pairs of each other.

Which line has a slope of 1/2 and goes through the point (2,4)?

Answers

the line equation for its slope and one point is:
y - y1 = m(x - x1)
m is the slope, x1, y1 are the point coordinates, so lets substitute:
y - 4 = (1/2)(x - 2)
y = (1/2)x + 3

Verify the identity. Justify each step. tan (thetA) + cot (thetA) = 1 / sin (thetA) cos (thetA)

Answers

The verification of the given identity i.e. an (thetA) + cot (thetA) = 1 / sin (thetA) cos (thetA) so it should be explained below.

Verification of the identity:

Since

theta = t

tan t + cot t = 1/ sin t cos t

Now

sin t / cos t + cos t / sin t = 1 / sin t cos t

So,

( sin² t + cos² t ) / sin t cos t = 1/ sin t cos t

And, finally

1/ sin t cos t = 1 / sin t cos t

theta = t
tan t + cot t = 1/ sin t cos t
sin t / cos t + cos t / sin t = 1 / sin t cos t
( sin² t + cos² t ) / sin t cos t = 1/ sin t cos t
1/ sin t cos t = 1 / sin t cos t 

Ebony walked at a rate of 3 1/2 miles per hour for 1 1/3 hours. how far did she walk?

Answers

Answer:

She walked 4(2)/(3) miles

Step-by-step explanation:

Speed of ebony = 3(1)/(2) miles/hour

                           = (7)/(2) miles/hour

Time Taken =1(1)/(3) hours.

                   =(4)/(3) hours.

We are supposed to find how far did she walk i.e. Distance

Formula : Distance = Speed * Time

Distance = (7)/(2) * (4)/(3)

Distance = (14)/(3)

Distance = 4(2)/(3)

Hence she walked 4(2)/(3) miles
