Answer:
Step-by-step explanation:
If AB is a tangent of a circle, then the angle B is right angle. Therefore the triangle ABC is a rigth triangle.
BC and x are the radius of a circle. Therefore BC = x.
Use the Pythagorean theorem:
We have
Substitute:
<em>subtract 6400 from both sides</em>
Answer:
1. No
2. 90 and 180
3. 9
4. 150 as consecutive angles
5. 73
6. x+x+2x+2x = 180
6x = 180
x = 30
7. 3x+2y+24=180
3x+2y +24=180
3x+2y=180-24
3×32 +2y= 156
y=60/2
y=30
when, y=24
3x+2y+24=180
3x+2×24-180-24
3x=-156-48
x=108/3
x=34.444
Answer:
I got -45.1 but idek if its right or not
Answer:
The length is 13
Step-by-step explanation:
w+w+l+l= perimeter
if the length is 3m less than twice the width then let's do some math.
42 divided 2 =21. so the width and length of one side have to equal 21. For example, let's use 8 as the width. The length would be twice(16) minus three(13) 13 plus 8 is 21. WOW it equals half of it so no we know the length is 13 and the wdith is 8.
