Answer: 12.56
Step-by-step explanation:
We know that
cos A=adjacent side angle A/hypotenuse
adjacent side angle A=24 units
hypotenuse=26 units
cos A=24/26-----> 12/13
cos B=adjacent side angle B/hypotenuse
adjacent side angle B=10 units
hypotenuse=26 units
cos B=10/26------> 5/13
the answers are
cos A=12/13
cos B=5/13
cot A=adjacent side angle A/opposite side angle A
adjacent side angle A=24 units
opposite side angle A=10 units
cot A=24/10------> cot A=12/5
cot B=adjacent side angle B/opposite side angle B
adjacent side angle B=10 units
opposite side angle B=24 units
cot B=10/24------> cot B=5/12
Answer:
Use SIN COS TAN
Step-by-step explanation:
5.5/4=x/100
4x=550
x=137.5
the water tower is 137 ft. 6 in. tall.
Answer:
<h2>x = 54</h2>
Step-by-step explanation:
The line is tangent. Therefore, the angle between the tangent and the radius is the right angle.
We know: the sum of the angles measures in a triangle is 180°.
Therefore we have the equation:
<em>combine like terms</em>
<em>subtract 126 from both sides</em>
