tim and luke start a lawn-mowing business and buy a lawnmower for $325. they plan to charge $25 to mow one lawn. which inequality can be used to find x, the minimum number of lawns they need to mow if they wish to earn a profit of at least $1000?
a) 25 ≤ 325x + 1000x
eliminate
b) 25 ≥ 325x + 1000x
c) 25x ≤ 325 + 1000
d) 25x ≥ 325 + 1000

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
