Find the value of x in each triangle. ( pls i need this is a test grade)

answer:

i think x is 70

step-by-step explanation:

a straight line is 180. therefore the side with no x is 40 and when you add the 3 inner sides of a triangle it also has to be 180.

therefore the 40+x+x=180

the x's are the same value because its iscoceles

so 2x=140

x=70

positive

step-by-step explanation:

the quadrant is facing upwards

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
