Answer:
The answer is 20 because when you divide 56 by 2.8 you get 20
You have two triangles, ADC and ABC.
Sides AD and AB are congruent.
Sides DC and BC are congruent.
Side AC is congruent to itself.
By SSS, triangles ADC and ABC are congruent.
Corresponding parts of congruent triangles are congruent.
That means that angles DAC and BAC are congruent.
Angles DCA and BCA are congruent.
Since m<DAC = 32, then m<BAC = 32
Since m<DCA = 41, then m<BCA = 41.
Now you know the measures of two angles of triangle ABC.
The measures of the interior angles of a triangle add to 180.
You can find the measure of angle B.
m<BAC + m<B + m<BCA = 180
32 + m<B + 41 = 180
m<B + 73 = 180
m<B = 107
Answer:
y - 3 = (2/5)(x + 2)
Step-by-step explanation:
Start with the general point-slope form of the equation of a straight line:
y - k = m(x - h). Now substitute -2 for h and 3 for k, and also 2/5 for m:
y - 3 = (2/5)(x + 2)
I quickly did this on paper and here is my answer I’m not 100% sure I’m correct but here it is
In 1 hour the boats will be 15 miles apart. In 3 hours the boats will be 45 miles apart.
Hope this helps :D
Answer:D ( if you add +4 to the (x + 3)^2)
Step-by-step explanation:
Parent function is f(x) = x^2
A translation 3 units left gives y = )x + 3)^2
- and 4 up gives y = (x + 3)^2 + 4 - vertex form.
Standard form :
y = x^2 + 6x + 9 + 4
= x^2 + 6x + 13.
