Answer:
I'm pretty sure the answer would be 2 but correct me if I'm wrong
Answer:
29.4, 17
Step-by-step explanation:
The short leg is 1/2 of the hypotenuse in a 30-60-90 triangle, so y = 17
The long leg is the short leg times sq rt of 3, x = 29.4
Answer:
-2.4 + 3.2t
Step-by-step explanation:
To combine the like terms, add both the numbers with the variable t together and the others without together.
-3.6+1.2= -2.4
-1.9t + 5.1t = 3.2t
Putting the sums together you should get:
-2.4 + 3.2t
If you're confused about how to subtract/add negative numbers, I like to ignore the sign--depending on what it is of course. For example, I rewrite -3.6+1.2 as 3.6-1.2. When you get the answer for that (2.4), add a negative symbol in front because the negative number was greater than the positive. I hope that helps rather than confusing you.
Answer:
x = 7
Step-by-step explanation:
This is an isosceles triangle
This means two angles are identical
There are 2 angles with the size 9x-25
Now you should add all of the angles together
104 + 9x-25 +9x-25
Then simplify this
54 + 18x
You should know that angles in a triangle add up to 180
54 + 18x = 180
Subtract 54 from both sides
18x = 126
divide both sides by 18
x = 7
