Answer:
see below
Step-by-step explanation:
We can find <C by adding all three angles in a triangle
<DBC + <C + <BDC = 180
30+ <C + 90 = 180
Combine like terms
120 + <C = 180
Subtract 120 from each side
120-120 + <C = 180-120
<C = 60
We can find <ABD by adding all three angles in a triangle
<ABD + <A + <BDA = 180
<ABD + 35 + 90 = 180
Combine like terms
< ABD +125 = 180
Subtract 180 from each side
< ABD +125-125 = 180-125
<ABD = 55
<ABC = <ABD + <DBC
= 55 + 30
< ABC = 85
The correct answer is 15
<span>4 + (x/3) = 9 </span>
<span>(x/3) = 9 - 4 </span>
<span>(x/3) = 5 </span>
<span>x = 15 </span>

Step-by-step explanation:
Answer:
1303.45 cm
Step-by-step explanation:
The triangles formed by a rod and its shadow and a tree and its shadow are similar triangles, so the ratios of their heights to the lengths of their shadows are equal.
Let x be the height of the tree. Setting the ratios equal, we get:
180/116 = x/840
Solve for x:
x = 840 * (180/116)
x ≈ 1303.45 cm
