Answer:
<h2>7.4inches</h2>Step-by-step explanation:
Check the attachment for the diagram. Sine rule will be used to get the unknown side of the triangle.
According to the rule;
Given w = 3 in, ∠W=23° and ∠U=73°, on substituting into the equation above to get u we have;
The length of u is 7.4inches to nearest 10th of an inch
Answer:
Step-by-step explanation:
<u>Slope-intercept form of a linear equation:</u>
where:
<u>Rearrange</u> the given equation so that it is in <u>slope-intercept form</u>:
Therefore, the slope of the given equation is -⁵/₇.
If two lines are <u>perpendicular</u> to each other (at right angles), the <u>product of their slopes</u> will be -1. Therefore, their slopes will be negative reciprocals of each other.
Therefore, the slope of the line perpendicular to the given equation is:
<u>Substitute</u> the found <u>slope</u> and the <u>given point</u> (6, -5) into the <u>slope-intercept formula</u> and solve for b:
<u>Substitute</u> the found slope and the found value of b into the <u>slope-intercept formula</u> to create the equation for the <u>perpendicular line</u>:

Answer : 7.5 ft
Step-by-step explanation:
when the length of the shadow is 8ft, the actual height of the man = 5ft
8:5
let the giraffe be 'x' ft tall.
if the length of the shadow is 12ft, actual height = x ft
12:x
8:5 x 12:x
×
x=
x=7.5 ft
Therefore, the giraffe is 7.5ft tall.
