Answer:
x =8.34654305
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent / hypotenuse
cos 33 = 7/x
Switching places with the x and the 33
x = 7/ cos 33
x =8.34654305
Answer:
155.7
Step-by-step explanation:
Use what you know.
Segment AC is 130 ft
Segment CD is 70ft
If you use the Pythagorean Theorem, in this case being = +
To find segment CE, you would do r-70
So, = +
= 16,900 + -140r + 4900
Add the -140r to the left side and then get rid of the two . Then Add 16,900 and 4900 together
You'll end up with 140r = 21,800
Divide 140 on each side.
Your final answer will be 155.7 (rounded to the nearest tenth)
Answer:
The perimeter of a shape is the sum of the measurements of all sides. Since a rectangle have equal lengths and widths, you can just add the numbers twice.
So, 15 + 15 + 8 + 8. So the perimeter is 46 cm.
