Convert the angle \theta=\dfrac{8\pi}{9}θ=

Olegator [25]

Answer:

160°

Step-by-step explanation:

-Given the angle in radians as $\theta=\dfrac{8\pi}{9}\ rad$

-We know that $1 \ rad=\frac{180}{\pi}\textdegree$

-Let our angle theta be X

#We therefore equate and cross multiply:

$1\ rad=\frac{180}{\pi}\\\\\frac{8\pi}{9}=x\\\\\therefore X=\frac{180}{\pi}\times \frac{8\pi}{9}\\\\=160\textdegree$

Hence, angle θ is 160°

Answer:

b = 2A/h

b = 6 inches

Step-by-step explanation:

$A = \frac{1}{2} bh \\ \\ 2A =bh \\ \\ \purple{b = \frac{2A}{h}} \\ \\ plug \: A = 12 \: and \: h = 4 \\ \\ b = \frac{2 \times \cancel{12}}{ \cancel4} \\ \\ b = 2 \times 3 \\ \\ b \: = 6 \: in$
