The length of the hypotenuse, line segment ac, in right triangle abc is 25 cm. the length of line segment bc is 15 cm. which is the approximate measure of angle acb? a)31.0° b) 36.9°c) 53.1° d)59.0°

Choice C) 53.1 degrees

------------------------------------------------------------------------------------------

Explanation:

Check out the attached image below for the drawing of the right triangle.

Let theta = angle ACB be the reference angle

According to this reference angle, the adjacent side BC is 15 while the hypotenuse is AC = 25. Use the cosine ratio and the arccosine (or inverse cosine) function to solve for the approximate angle. Make sure your calculator is in degree mode

cosine(angle) = adjacent/hypotenuse

cos(theta) = BC/AC

cos(theta) = 15/25

cos(theta) = 3/5

theta = arccos(3/5)

theta = 53.1301

theta = 53.1

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

positive

step-by-step explanation:

the quadrant is facing upwards
