Answer:
14 + k = 3k - 2
- k - k
14 = 2k - 2
+2 +2
16 = 2k
8 = k

Answer:

Here, the given 2 angles are complementary angles. The sum is <u>90 degrees</u> as indicated by the right angle symbol.




Answer:
57.9°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between trig functions and sides of a right triangle. Here, you're given the side adjacent to the angle of interest, and the hypotenuse of the triangle. This suggests the CAH relationship is the one of interest:
Cos = Adjacent/Hypotenuse
cos(angle) = (741 ft)/(1393 ft)
angle = arccos(741/1393) ≈ 57.863° . . . . . use the inverse cosine function
angle ≈ 57.9°
The wire makes an angle of approximately 57.9° with the ground.
Answer:0.0375
Step-by-step explanation: divide 1 from 10 and 3 from 8 then divide those answers
The zeros of the equation are <span>8+i and 7. however since this is a third degree polynomial, the other root missing is the conjugate of the imaginary term 8-i, which is 8 +i. We multiply then ( x- 8 - i) *( x- 7)* (x - 8 + i).The expansion is (x2 - 16x + 1 --1 ) *(x-7) = </span><span>(x2 - 16x + 2 )(x-7) = x3 -7 x2 -16x2 +112 x +2x -14 = x3 -23 x2 + 114 x -14</span>
