The complete question in the attached figure

we have that

250°----------> belong to the third quadrant

if 2pi radians-------------> 360°
X-------------------------> 250°
X=250*2pi/360------------> 1.39 pi radians
then
<span>the radian measure of the central angle is 1.39pi
</span>
hence

The length of the base of a triangle is twice its height. if the area of the triangle is 196 square kilometers, find the height

NISA [10]

Area = 1/2 x base x height

Let the height be x.
Height = x
Base = 2x

Area of triangle = 1/2 x base x heght

Plug base and height into the variables:
(1/2)(2x)(x) = 196

Combine like terms:
x² = 196

Square root both sides:
x = 14

Find Base and height:
Base = x = 14 km
Height = 2x = 2(14) = 28 km

Answer: Height = 28km

Billy has 2 cats and one of them ate 3 oatmeal bowls. If they both eat 3 oatmeal bowls how much sugar should they all together h

9966 [12]

3 x (2/3) = 2

2 x 2 = 4

If both cats eat 3 oatmeal bowls, they should have 4 cups altogether.

2 x 23.8888 = 47.7776

4 x 23.8888 = 95.5552

47.7776 + 95.5552 = 143.3328

If one cat eats 2 fish plates and the other cat eats 4 fish plates, they use 143.3328 pounds altogether.
