Answer: Option D
Step-by-step explanation:
Hey there!
Here; Looking at it we can state that it is a Right angled triangle.
<u>And</u><u> </u><u>must</u><u> </u><u>use</u><u> </u><u>the</u><u> </u><u>Pyth</u><u>agoras</u><u> </u><u>relat</u><u>ion</u><u> </u><u>if</u><u> </u><u>the</u><u> </u><u>trian</u><u>gle</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>Right</u><u> angled</u><u> triangle</u><u>.</u>
<u>So</u><u>,</u><u> </u><u>let</u><u>'s</u><u> </u><u>wo</u><u>rk</u><u> on</u><u> </u><u>it</u><u>.</u>
Let ABC be a triangle.
Taking reference angle as C, we get;
perpendicular= 3m
Hypotenuse= 7m
Base = xm

Answer:
6
Step-by-step explanation:
Deisha's build rate = 1 fence per 15 hours = 1/15 fences per hour
Travis's build rate = 1 fence per 12 hours = 1/12 fences per hour
Working together, their combined rate is 1/15 + 1/12 = 3/20 fences per hour
So it takes them 20/3 = 6 2/3 hours per fence
The answer is: 8 red marbles!
This is because the equation can be written out like this
Blue to red - 3:2
Now it is, blue to red - 12:x
We have to think, what is the difference from the first equation to the second. We know the number 3 times 4 = 12, so we would do the same for the red, 2 times 4=8
If this helped, give me brainliest :)
Use the app photo math you will get all the answers fast
1) The line will need to be vertical down the point of x, meaning draw a line down point x. Perpendicular lines look similar to t’s
2.) Same thing, just draw a line through point O and the line. They should look similar to t’s
Hope this helped!! I understand math can get really hard, soon it’ll all be over :)
