Answer:
65.5 degrees
Step-by-step explanation:
Triangles add up to 180 degrees. So, the last value has to make the rest add up to 180.
Let x be the unknown degree.
61 + 53.5 + x = 180.
You cancel out the 61 and the 53.3 by subtraction, making you get
x = 65.5

I think the answer is B. because the sum of the 2 smaller numbers is greater than the 3rd number.
a. 8+6 = 14 ; 14 is less than 16 ; wrong
b. 8+6 = 14 ; 14 is greater than 10 ; correct
c. 7+6 = 13 ; 13 is less than 14 ; wrong
d. 6+7 = 13 ; 13 is less than 20 ; correct
Hope this helped☺☺
You can consider the tree perpendicular to its shadow, therefore you get a triangle rectangle of which you know the two legs and you need to find the angle between the shadow and the hypothenuse, opposite to the tree.
In this case, the angle α can be easily found with trigonometry:
tan α = (opposite side / adjacent side)
Therefore:
α = tan⁻¹ (tree / shadow) = tan⁻¹ (10 / 14) = 35°
NOTE:
tan⁻¹ is sometimes found written as arctan.
Ok so he had to pay (i'll say 17 because it's easier to type but understand it's 16.99) 17 dollars up front, and he paid 0.88x, x being miles driven. This means for how many miles he's driven, the equation would look like 17 + 0.88x. Set this equal to 203.55 to find out how many miles he drove. Solving this you get 212 miles.
