A painter is going to apply a special coating to a triangular metal plate on a new building. Two sides

viva [34]

Answer:

$Area = 90.03cm^2$

Step-by-step explanation:

Given

$s_1 = 14.9$

$s_2 = 14.7$

$\theta = 124$ --- angle in between

Required

The area of the plate

Since $\theta = 124$ is between $s_1$ and $s_2$

The area is:

$Area = \frac{1}{2} * s_1 * s_2 * \sin(\theta)$

$Area = \frac{1}{2} * 14.9 * 14.7 * \sin(124.7)$

$Area = \frac{1}{2} * 14.9 * 14.7 * 0.8221$

$Area = 90.03cm^2$

Center ( 9,-8 ), passes through ( 19,22 )

katovenus [111]

Center at (h,k) and radius r is
(x-h)²+(y-k)²=r²

so given
center at (9,-8)

(x-9)²+(y-(-8))²=r²
(x-9)²+(y+8)²=r²

input the point (19,22) to find r²
x=19 and y=22
(19-9)²+(22+8)²=r²
10²+30²=r²
100+900=r²
1000=r²
10√10=r

well, the equation is
(x-9)²+(y+8)²=1000
