Answer:
26.0
Step-by-step explanation:
Angle X is the largest angle in the triangle, so is opposite the longest side. That is, YZ must be longer than XY, so the only viable answer choice is ...
26.0
___
You can figure the length from the Law of Cosines:
YZ^2 = XY^2 + XZ^2 -2(XY)(XZ)cos(X) = 449.44 +96.04 -415.52cos(108°)
YZ = √(673.88) ≈ 25.96
YZ ≈ 26.0
_____
Your sense of number relationships can solve a lot of problems, particularly multiple-choice problems. It pays to understand how angle measures and triangle side measures are related to each other.
Let p represent her present test point total, and t represent the necessary average on the next two tests.
.. p +2t ≥ 450 . . . . she wants an A grade after the next two tests
.. t ≥ (450 -p)/2 . . . her required average on the next two tests
Answer:
1.18 kilometers
Step-by-step explanation:
The middle school is 2.72 kilometers from Marshal house
The school is also 1.54 kilometers away from Ryan house
Therefore the distance of Marshal house from the school can be calculated as follows
= 2.72-1.54
= 1.18 kilometers
If you are solving for x then here’s how:
(3x2 + 4x - 12) = (x + 5)
Remove the x on the left by remove one x from both of the sides.
(3x2 + 3x - 12) = 5
Add 12 onto both sides
(3x2 + 3x) = 17
Multiply
(6 + 3x) = 17
Take away 6 from both sides
3x = 11
Divide by 3 on both sides
x = 3.666 recurring
