The value of x and the value of y

Mathematics

Answer:

x= 60 y=50

Step-by-step explanation:

First to find x, all the degrees in a triangle add up to 180 degrees. So 50+70+x=180 which is also 120+x=180 which means x=60. Y is the exterior angle of x and a missing angle. Let's substitute the missing angle with the variable z. 60+50+z=180 which is 110+z=180 which means z is 70. So 180-x+z=y. 180-60+70=y which means y is equal to 50. Hope this helps!

X=60
y=50
a triangle is 180° so if you subtract 70 and 50 from that you get 60=x
a straight line is also 180° so use the same method above from the left triangle and subtract all from 180 to get y

If a weak monoprotic acid, HA, is titrated with strong base, what is NOT true at the half equivalence point?pH = pKapH = 7.0[HA]
leonid [27]

Answer:

pH can be different from 7 ( second statement is false)

Step-by-step explanation:

since

pH=pKa + log [A-]/[HA]

at half of the equivalence point

[HA]= [A-] (third statement is true)

and therefore

pH = pKa (first statement is true)

since pH = pKa , pH can be different from 7 ( second statement is false)
