Answer:

x = 127 degrees

Step-by-step explanation:

By the external angle of a triangle theorem:-

x + 5 = 79 + m < ACB

m < ACB = 180 - x, so:-

x + 5 = 79 + 180 - x

2x = 79 + 180 - 5 = 254

x = 127 ( answer)

Use the fact that the length of an arc intercepted by an angle is proportional to the radius to find the area of the sector give

Hunter-Best [27]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta r^2}{2}~~
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad radians\\
------\\
r=3\\
\theta =\frac{\pi }{4}
\end{cases}\implies A=\cfrac{\frac{\pi }{4}\cdot 3^2}{2}\implies A=\cfrac{\frac{9\pi }{4}}{2}
\\\\\\
A=\cfrac{9\pi }{4}\cdot \cfrac{1}{2}\implies A=\cfrac{9\pi }{8}$

4. Make up a system of equations with infinite<br> solutions

Taya2010 [7]

Answer:

$\left \{ {{x+y=1} \atop {2x+2y=2}} \right.$

Step-by-step explanation:

As long as the two equations represent the same straight line on the coordinate plane (they overlap), there will be infinite many intersections and infinite number of solutions.
