Answer:
19.8 cm
Step-by-step explanation:
Using the Pythagorean theorem , the Square of the distance between the top of the piece and the Shadow Is the sum of the height of the piece. and the lenght of the shadow. basically Just build a triangle with the 3 points you are given: height of the piece, lenght of the shadow and distance between the 2. so it's sqrt(13^2+15^2) = sqrt(394) =19.8 cm
Answer:
C
Step-by-step explanation:
We know a straight angle is 180 degrees ( a straight line).
Looking at the figure, we can say that A + F + E = 180 (since it creates a straight line).
We know A = 45, E = 85, plugging these into the equation, we can solve for F:
A + F + E = 180
45 + F + 85 = 180
130 + F = 180
F = 180 - 130
F = 50
Answer choice C is right.

What app will show the work
Answer:
-3k + 10
Step-by-step explanation:
-3k - (-8) + 2
-3k + 8 + 2 !!
-3k + 10 → simplified version of the given expression
!! → We got rid of the parenthesis by combining the two negative signs. The rules state that any 2 identical signs combined (in this case, - and -) equal a positive sign (+).
