The initial expression is:

$-10+\frac{r}{5}=1$

So we can solve for r so:

$\begin{gathered} \frac{r}{5}=1+10 \\ r=11\cdot5 \\ r=55 \end{gathered}$

Please help: In Δ ABC, sin A=88, sin B=42, and a =17, find the length of b.

iren2701 [21]

Answer:

Step-by-step explanation:

Use the law of sines.

$\frac{sin A}{a} = \frac{sin B}{b} \\$

Plug values in.

$\frac{sin88}{17} = \frac{sin42}{b}\\$

Cross multiply.

$bsin88 = 17sin42\\b = 11.38$

Hope that helps.

You design the wooden picture frame and paint the front surface.

Hitman42 [59]

Answer:

a) 8x + 28
b) 68 in²

Step-by-step explanation:

Area of the frame with picture:

A = lw
A₁ = (x + 4)(x + 7) = x² + 11x + 28

Area of the picture:

A₂ = x(x + 3) = x² + 3x

Area of the wooden frame is the difference of the above values:

A₃ = A₁ - A₂
A₃ = x² + 11x + 28 - x² - 3x
= 8x + 28

When x = 5, the picture frame area is:

A₃ = 8*5 + 28 = 40 + 28 = 68 in²
