Answer:
120
Step-by-step explanation:
Angles opposite to equal sides are equal .
30 + 30 + x = 180 {Angle sum property of triangle}
60 + x = 180
x = 180 - 60
x = 120
When you multiply by 1/10 you normally add another 0:
1/10 * 0.092=0.0092
It forms a Triangle, in which base is shadow, and height of the tree is perpendicular.
So, Tan Ф = P / B
Tan 28 = P /18
0.53 * 18 = P [ Tan 28 = 0.53 ]
P = 9.6
In short, Your Answer would be Option D
Hope this helps!
Answer:
2a-6=a
Step-by-step explanation:
The keyword "times" lets us know we need to multiply 2 and a and "less" shows us we need to subtract 6 from that.
