A highway runs east-west between two towns C and B that are 25 km apart. Town A lies 15 km directly north from C. A straight road is built from A to meet the highway at D which is equidistant from A and B. Find position of D on the highway.
find distance AB
Using Pythagorian
AB^2 = 15^2+ 25^2
then find Point M which is midpoint of AB
AM=MB= 1/2 (AB)
now take a look at the right triangle ABC
tan(
Answer:
22°
Step-by-step explanation:
cos B = (c2 + a2 − b2)/2ca
cos B = (
+
-
)/ 2(10)(6)
cos B = .925
B = 22.33
Answer:
A
Step-by-step explanation:
Work with the two points
Formula
m = (y2 - y1)/(x2 - x1)
Givens
y2 = 3
y1 = 1
x2 = - 2
x1 = - 5
Solution
m = (3 - 1) / (-2 - - 5)
m = 2 / (-2 + 5)
m = 2 / 3
Answer: A
Hi!
I've included an image showing the shape divided into 3 rectangles. We're going to find the area of each rectangle.To find the area of a rectangle,
multiply the length times the width. The red rectangle:8 · 9 = 72
The area of the red rectangle is 72in.
The orange rectangles:The orange rectangles have the same area.
10 · 3 = 30
30 + 30 = 60
The area of both orange rectangles is 60in.
72 + 60 = 132
The answer is
132 square inches.Hope this helps! :)
