Step-by-step explanation:
he triangle is isosceles.
The leg-to-hypotenuse ratio is 1:StartRoot 2 EndRoot.
The leg-to-hypotenuse ratio is 1:StartFraction StartRoot 2 EndRoot Over 2 EndRoot. The nonright angles are congruent. The ladder represents the longest length in the triangle.
3/4t=14
t=56/3
hope this helps!
It would be helpful to draw the figure from the problem statement above. Drawing it, would give you a right triangle shape where the base is equal to 10 ft + 8 ft = 18 ft with the angle of 40 degrees. We use knowledge on trigonometric functions to solve this.
tan (theta) = opposite side / adjacent side
tan 40 = x / 18
x = 15.10 ft
Answer:
We have (x 2
−2x) 10 =x 20 (1− x
2 ) 10
and since x 20 multiplies every term in the expansion of (1− x
2 ) 10 we have in this expansion to seek the coefficient of the term which contains
x 4
1
Hence the required coefficient
10
C 4 (−2) 4
= 1.2.3.4 10.9.8.7×16=3360
