Step-by-step explanation:
:)
The questions are illustrations of trigonometry ratios and right triangles
- The value of x is 11.8310
- The tree is 23.3154 feet tall
- The depth of the sub is 376.7770 meters
Trigonometry ratio
Trigonometry ratios are very useful in determining the measure of angles, and the side lengths of a right triangle.
<h3>Question 1</h3>
The value of x is calculated using the following sine trigonometry ratio

Make x the subject

This gives

Hence, the value of x is 11.8310
<h3>Question 2</h3>
This question is illustrated by the first diagram in the attached figure
The height (h) of the tree is calculated using the following tangent trigonometry ratio

Make h the subject

This gives

Hence, the tree is 23.3154 feet tall
<h3>Question 3</h3>
This question is illustrated by the second diagram in the attached figure
The depth (h) of the sub is calculated using the following tangent trigonometry ratio

Make h the subject

This gives

Hence, the depth of the sub is 376.7770 meters

Answer:
7y+5x=76
Step-by-step explan
A (-4,8) and B (6,3)
First find the slope;
m= (y2-y1)/(x2-x1)
m=(3-8)/(3+4)
m=-5/7
now using equation of line
y-y1= m(x-x1)
y-8=-5/7 (x+4)
y-8=(-5x+20)/7
7(y-8)= -5x+20
7y-56=-5x+20
7y+5x=20+56
7y+5x=76
Note that 1 meter = 100 centimeters, so 1.3 meters = 130 centimeters
It grew another 22 cm
130 + 22 = 152
152 cm is your answer
hope this helps
