Answer:
132 m
Step-by-step explanation:
Refer to attachment for figure.
In smaller triangle with angle theta , we have ,
⇒ tanθ = p/b
⇒ tanθ = h/121m
⇒ tanθ = h/121 m
<u>In</u><u> </u><u>triangle</u><u> </u><u>with</u><u> </u><u>angle </u><u>9</u><u>0</u><u>-</u><u>∅</u>
⇒ tan(90-θ) = p/b
⇒ cot θ = h/144 m
Multiplying these two ,
=> tanθ . cotθ = h/121 m × h/144m
=> 1 = h²/ (121 m × 144m )
=> h² = 121m × 144m
=> h= √ ( 121m × 144m)
=> h = 11m × 12m
=> h = 132 m
<h2>Solution :</h2>
= 2x = 9
= x = 9 ÷ 2 ( transposing ×2 from LHS to RHS changes ×2 to ÷2 )
= x = 4.5
Therefore , x = 4.5 .
Answer:10.5
Area of a triangle =bh/2
=3x7/2
=21/2
=10.5
Step-by-step explanation:
The correct options related to the correlation coefficient are basically that it presents the strength of the relationship,it presents the direction of the relationship and it varies from -1 to 1.
Given four options related to correlation coefficient.
We are required to choose the correct options related to correlation coefficient.
The correlation coefficient is basically the specific measure that quantifies the strength of the linear relationship between two variables in a correlation analysis. The coefficient is basically symbolize with the r in a correlation report.
The correct options related to correlation coefficent are:
- Presents the strength of the relationship,
- Presents the direction of the relationship,
- Varies from -1 to 1.
Hence the correct options related to the correlation coefficient are basically that it presents the strength of the relationship,it presents the direction of the relationship and it varies from -1 to 1.
