Solve each equation.Show your work. Can someone help me please??

Inga [223]

Answer:

1/2a = -5

a = (-5 x 2) : 1

a = -10

8 - b = 9,5

b = 8 - 9,5

b = -1,25

0,1 = -10c

c = 0,1 : -10

c = -0,01

I hope it's helpful.

Calculate the side lengths a and b to two decimal places

Answer:

Option (D)

Step-by-step explanation:

In the picture attached,

An obtuse angle triangle ABC has been given.

By applying Sine rule in the triangle,

$\frac{\text{SinB}}{b}=\frac{\text{SinA}}{a}=\frac{\text{SinC}}{c}$

Since, m∠A + m∠B + m∠C = 180°

45° + 110° + m∠C = 180°

m∠C = 180°- 155° = 25°

$\frac{\text{Sin110}}{b}=\frac{\text{Sin45}}{a}=\frac{\text{Sin25}}{7}$

$\frac{\text{Sin110}}{b}=\frac{\text{Sin45}}{a}=0.060374$

$\frac{\text{Sin110}}{b}=0.060374$

b = $\frac{\text{Sin110}}{0.060374}$

b = 15.56

b ≈ 15.56

$\frac{\text{Sin45}}{a}=0.060374$

a = $\frac{\text{Sin45}}{0.060374}$

a = 11.712

a = 11.71

Therefore, Option (D) will be the answer.
