Circle B =
Step-by-step explanation:
Circumference of a circle =
Since you are given the radius, you put it in place of r
Circle A = 
Circle B=

Given a fragpole which makes a right angle with the point of observation with the angle of elevation as 50°.
Let x be the height of the flagpole, then

Therefore, the <span>equation that could be used to find the height of the flagpole is
</span><span>x/5 = sin 50</span>
Answer:
<em>a=$10</em>
<em>c=$3</em>
Step-by-step explanation:
Step one:
given data
let adults tickets be a
and child tickets be c
so
Roy's purchase
6a+2c=66------1
Elisa's purchase
5a+4c=62-------2
Hence, the system of equations
<em>6a+2c=66------1</em>
<em>5a+4c=62-------2</em>
<em>solving simultaneously</em>
<em>6a+2c=66------1 x2</em>
<em>5a+4c=62-------2 x1</em>
<em />
<em> 12a+4c=132</em>
<em> -5a+4c=62</em>
<em> 7a=70</em>
<em>divide both sides by 7</em>
<em>a=$10</em>
<em />
<em>put a=70 in 1</em>
<em>6(10)+2c=66------1</em>
<em>60+2c=66</em>
<em>2c=66-60</em>
<em>2c=6</em>
<em>c=$3</em>
Answer:
x^2 + 3x + 5
Step-by-step explanation:
sum of the two given side = 2x^3 + 3x^2 + 3x -2
missing side = 2x^3 + 4x^2 + 6x + 3 - 2x^3 - 3x^2 - 3x + 2 = x^2 + 3x + 5
