15x - 25
The base angles are both 74°
Further explanation:
An isosceles triangle is a type of triangle that has two sides and two angles equal.
Let A, B and C be three angles
Let A=32°
If A is 32 then B and C will be equal
The internal angles of a triangle are 180°
So,
m∠A+m∠B+m∠C=180°
We know that B and C are equal
m∠B=m∠C
So putting the value of A and replacing C by B
32°+m∠B+m∠B=180°
32°+2m∠B=180°
2m∠B=180°-32°
2m∠B=148°
m∠B=148°/2
m∠B=74°
As
m∠B=m∠C
So
m∠C=74°
The base angles are both 74°

x≤-7
First , use the distributive property :
3(x-4)≥5x+2
3x-12≥5x+2
Subtract 5x on both sides :
3x-5x-12≥2
Now , add 12 on both sides :
3x-5x≥2+12
3x-5x≥14
Subtract the x's :
-2x≥14
Divide by -2 on both sides and watch what happens :
x≤-7 (notice that the inequality sign changed from "greater than or equal to" to "less than or equal to")
If we divide both sides of an inequality by a negative number , we change the inequality sign .
