Answer:

About 10.4 cm

Step-by-step explanation:

By the Law Of Sines:

\dfrac{6}{\sin 30}=\dfrac{b}{\sin 120} \\\\\\b=\dfrac{6}{\sin 30}\cdot \sin 120\approx 10.4\text{ cm}

Find the measures of two suplametery angles if their measures are in the givin ratio 2:3
geniusboy [140]

Answer:

Let the two supplementary angles be

we know sum of two supplementary angles is 180

2x + 3x = 180

5x = 180

x = 180/5

x = 36

2*36 = 72

3*36 = 108

Therefore the two supplementary angles are 72 and 108

Celia uses the steps below to solve the equation Negative StartFraction 3 over 8 EndFraction (negative 8 minus 16 d) + 2 d = 24.
Troyanec [42]

The error in the steps is that In step 1, she should have also distributed -3/8  over –16d, to get 3 + 6 d + 2 d = 24

<h3>Simplifying linear equations</h3>

Given the following equation as shown below

-3/8(-8-16d)+2d = 24

Step 1 Distribute -3/8 over the expression in parentheses

3 + 6d + 2d = 24

Simply the like terms

3 + 8d = 24

Subtract 3 from both sides of the equation.

8d = 24 - 3

8d = 21

d = 21/8

Hence the error in the steps is that In step 1, she should have also distributed -3/8  over –16d, to get 3 + 6 d + 2 d = 24
