Answer:
Part 1) 
Part 2) 
Part 3) 
Part 4) 
Step-by-step explanation:
step 1
Find the measure of angle C
we know that
The triangle ABC is a right triangle
so
Angle C is a right angle
therefore
step 2
Fin the measure of angle A
we know that
In the right triangle ABC
∠B+∠A=90° -----> by complementary angles
we have
substitute
step 3
Find the length side b
we know that
In the right triangle ABC
substitute the given values
step 4
Find the length side a
we know that
In the right triangle ABC
substitute the given values
what you do first is you times the F which will equal -2 which will give you an answer then you subtract that answer by 10 * by 200 than you have your answer
The value of 2.704 is .004 because it is 3 spaces to the right of the decimal point.
Answer:
x=3 and x=-5
Step-by-step explanation:
To find the x intercepts set y =0 and solve for x
0 = x^2+2x-15
Factor
What two numbers multiply to -15 and add to 2
5*-3 = -15
5+-3 =2
0 = (x+5) (x-3)
Using the zero product property
x+5=0 x-3 =0
x=-5 x=3
9514 1404 393
Answer:
(b) 5.66 mi
Step-by-step explanation:
You only need to eliminate the unreasonable answers to make the correct choice.
The hypotenuse of the right triangle is its longest side, so the unknown length must be less than 6. That eliminates the last two choices.
The unknown length cannot be less than the difference of the sides shown, so the unknown length must be more than 4. That eliminates the first choice.
The only reasonable choice is ...
B. 5.66 miles
_____
If you like, you can calculate the distance using the Pythagorean theorem.
AB² + 2² = 6²
AB = √(36 -4) = √32 ≈ 5.66 . . . miles
