In the following diagram HI || JK.What is the measure of Angles are not necessarily drawn to scale.
1 answer:
ANSWER
xº = 52º
EXPLANATION
Since segments HI and JK are parallel, we can see segment AK as a transversal:
So angle JKA and angle HIA are <em>corresponding angles</em> and they are congruent.
Then we have triangle HAI, and we have two of the angle's measures. The sum of the measures of the interior angles of a triangle is 180º:
Solving for x:

Answer:
B = 62.9ft
Step-by-step explanation:
The distance where she is from the oak tree is 75ft,
The angle of elevation the stone makes with the top of the oak tree is 40°
The height of the tree is x ft
See attached document for better illustration
Using SOHCAHTOA,
Tanθ = opposite/ adjacent
θ = 40°
Opposite = x ft
Adjacent = 75ft
Tan40 = x / 75
X = 75 × tan40
X = 75 × 0.8390
X = 62.92ft
The height of the oak tree is 62.9ft
