Answer:
9 and 11
Step-by-step explanation:
Angle a has a little square box in it, which means right angle, which is equal to 90 degrees.
Angle A = 90 degrees
Angle A m B and the 59 forms a straight line which needs to equal 180
Angle B = 180 - 59 - 90 = 31
Angle B = 31 degrees.
Angle C is a vertical angle with A and B, so Angle C = 90 + 31 = 121 degrees.
Angle D is a vertical angle with 59, so equals 59 degrees.
Given:
To find:
The correct equivalent equation.
Solution:
We have,
Taking sin on both sides, we get
Interchanging the sides, we get
Therefore, the correct option is 4.
The tree is 20 m tall .
Step-by-step explanation:
<h2>Given : </h2>
- 2m tall tree cast a shadow 4 m long .
=> 2 m tree = 4 m long
If we find shadow of 1 m tall tree = 4/2
=> we have to find height of 10 m tall tree which is .. = 4/2 × 10 = > 20 m
Answer:
4116
Step-by-step explanation:
2014
12000÷10=1200 (10%)
1200x3=3600
12000-3600=8400
2015
8400÷10=840
840x3=2520
8400-2520=5880
2016
5880÷10=588
588x3=1764
5880-1764=4116
