<u>Angle A = 30 degrees</u>
1) Use the Pythagorean Theorem:
-->
--> 144 + 48 =
--> 192 =
--> AC =
2) Figuring out the type of triangle it is
There's a formula on the sides of a certain type of triangle:
--> Hypotenuse: a, Short Leg: a/2, Longer Leg: a/2 *
That type of triangle perfectly matches the sides of our triangle: 12, ,
Therefore, this triangle is a 30, 60, 90 triangle.
3) Finding the measure of angle A
--> Angle B is given: 90 degrees
--> The angle that's between Sides AB and AC is 30 degrees
Finally, we can conclude that Angle A is 30 degrees
Answer:
Speed before applying brakes = 64.8
Step-by-step explanation:
The formula is given as:
Where
s is speed of car, and
d is length of skid marks
It is given that d = 175 ft, so we substitute and find the speed of the car before the brakes were applied.
Rounding to nearest tenth, that is 64.8
140.7 is the answer in a decimal
Answer:
The slope is negative 2 or (-2)
Step-by-step explanation:
Y2 - Y1
----------
X2 -X1
(0,2)
(1,0)
2 - 0
------- = 2/-1 = -2
0 - 1
Less = subtract
than =switch the order
product = multiply so
5 x -4 - 8
= -20 - 8
= -28
