Answer:add 6b and 7b 13b-10
Step-by-step explanation:
Answer:
BDC is half of mBC = 11°
Easily you see that C is A + BDC = 23°
Since C = 23° so mDC is twice = 46°
x
Answer:
14 x 14 = 196
10 x 14 x 1/2(basically just dividing by 2) = 70
70 x 4(four sides of triangles) = 280
Now let's add the areas together:
196 + 280 = 476 cm^2 is your answer.
Answer:
Approximate maximum height is <em>5 ft</em>

Step-by-step explanation:
---------- (1)
Differentiate equation (1) w.r.t <em>t </em>and equate it to zero (in order to determine maxima)



Substitute this value in equation (1)
