Answer:

66 degrees.

Step-by-step explanation:

angle 4 is 124, and angle 1 and 4 make 180 degrees. that means angle 1 is 56 degrees (180-124). and the total angle in a triangle is also 180 degrees.

Add 56 and 58, you'd get 114.

180-114=66

angle 2=66 degrees.

Marta is solving the equation S = 2πrh + 2πr2 for h. Which should be the result?

geniusboy [140]

Step-by-step explanation:

$S = 2\pi rh + 2\pi {r}^{2} h \\ \\ \therefore \: S = (2\pi r + 2\pi {r}^{2}) h \\ \\ \therefore \: S = 2\pi r(1 + {r}) h \\ \\ \huge \purple{ \boxed{\therefore \: h = \frac{S}{2\pi r(1 + {r})} }}\\$
