Step-by-step explanation:
Let's finish strong! Maybe we'll have some time for some fun activities!
Let's start with angle B.
Remember that the internal angle of a triangle will always equal 180.
We have a rignt angle (90), a known angle (54), and unknown B.
We can establish a simple equation to solve for B.
33% done!
To solve for the other sides of the triangle, we'll need to use our trig functions! Boo! I know, but they are super handy! Let's see them in action.
Remember that ol' saying - some old hippy caught another hippy tripping on acid. SOH, CAH, TOA.
sin = opposite over hypotenuse, cos = adjacent over hypotenuse, tan = opposite over adjacent.
A little fancy calculator work and we're 66% done! whew!
If we know a and the third side as being 23, we can just use the Pythagorean theorem
Done! Wow! That's feels good. Great job!
n - 12 = -9
Add 12 to both sides to isolate the variable n.
n = -9 + 12
n = 3
B) n = 3
Answer:
C. is the correct answer.
Step-by-step explanation:
The sentence "Five times a minus two is equal to t" corresponds with 5x - 2 = t exactly.
This means that it is correct.
Following BODMAS,
start with the inner brackets first so, 36-5(21/8) + 27 .
Then you multiply: 36 - 105/8 + 27
Work from left to right: answer should be 399/8
Hope this helps :)
Can always check with calculator too XD
