Answer:

k = 10

Step-by-step explanation:

There are 180 degrees in a straight line, so ZYX must be 85 degrees. There are also 180 degrees in a triangle, so YZX + ZXY = 115.

4k + 5 + 6k + 10 = 115

10k + 15 = 115

10k = 100

k = 10

Can u please find the length of BC round to the nearest tenth

PolarNik [594]

Answer:

Step-by-step explanation:

Using sine rule

SinA/a = SinB/b = SinC/c

A = 84° a = BC, C = 51°, c = 16

Sin84/BC = Sin51/16

Cross multiply

BC Sin51 = 16 × Sin84

BC = 15.91/Sin51

BC = 20.48unit

A certain scale has an uncertainty of 4 g and a bias of 2 g. A single measurement is made on this scale. What are the bias and u

Fed [463]

Answer: 0.8

Step-by-step explanation:

given data:

uncertainity = 4g

bias = 2g

solution:

σX =0.2 and σY = 0.4

σcX

= 3σX

= 4(0.2)

= 0.8
