Answer:
B = 45°
BC = 14 km
AB = 14√2 km ≈ 19.80 km
Step-by-step explanation:
If one acute angle (A) of a right triangle is 45°, then the other one is also:
... 180° -90° -45° = 45°
The sides opposite these congruent angles are the same length, 14 km in this case, and the hypotenuse is found from the Pythagorean theorem to be √2 times either leg length.
... AB² = AC² +BC²
... AB = √(AC² +BC²) = (14 km)√(1² +1²) = 14√2 km
We can factor this polynomial using grouping. What we do is split the 36p into into parts so that we can factor the polynomial one half at a time.
To do so, we first multiply the leading coeffient by the constant. In other words, a times c where
. After multiplying 4 and 81, we get 324. Now we need to find two numbers that multiply to be 324 and add to be 36.
The factors of 324 are: 1, 2, 3, 4, 6, 9, 12,18, 27, 36, 54, 81, 108, 162, and 324.
The pair of numbers that works in this case are 18 and 18 since 324 is a perfect square.
Now we split the 36p:
Now factor both halves.
We have a common binomial of 2p+9 that can be factored out it get
or
Answer:
17.5
Step-by-step explanation:
The area of a triangle is (height*base)divided by two
(the eight is really unnecessary)
so 7=base
8=height
7*5=35
35/2=17.5
C, if they want to look at the record of the player c is the best options
