No, it is not a prim number
Answer: The correct answer is (C) 8.8
Step-by-step explanation: The given triangle has two sides and two angles given. However it is not a right angled triangle. In order to calculate an unknown side or angle in questions such as this, we shall apply the sine rule, which states;
a/SinA = b/SinB = c/SinC
Where the reference angle is that facing the line (that is, SinA is the angle facing line a, etc).
To calculate x, we shall use angle 28 as the reference angle. We have also been given line 8.2, and the angle facing it is derived as
180 - (28 + 126)
= 180 - 154
= 26
If the angle facing line 8.2 is 26, then the sine rule can be applied as follows;
x/Sin28 = 8.2/Sin26
By cross multiplication we now have
x (Sin26) = 8.2 (Sin28)
x = [8.2 (Sin28)]/Sin26
x = (8.2 x0.4695)/0.4384
x = 8.7817
Approximately x = 8.8 (to the nearest tenth)
The answer is 27
3x + 5x +18 =90
8x=72
x=9
Angle1=3x=3*9=27
The first step of Pemdas is parenthesis.
We start with (176-32+13)
Then we move do addition:
32 + 13 = 45
Now addition:
176-45=131.
Now we can do division:
131 divided by 17 = 7.705 (With only 3 decimals)

Answer:
11.8 meters
Step-by-step explanation:
The triangle drawn is a right triangle. Two of its side lengths are given. The Pythagorean theorem tells you how those relate to the third side.
The sum of the squares of the legs of the triangle is equal to the square of it hypotenuse.
(?)² + 34² = 36²
(?)² + 1156 = 1296 . . . evaluate the squares
(?)² = 140 . . . . . . . . . . subtract 1156 from both sides
(?) = √140 . . . . . . . . . take the square root
(?) ≈ 11.8 . . . meters
The length of the shadow is about 11.8 meters.
