EC bisects so m<BEC = m<CED

11x - 12 + 2(4x + 1) = 180
11x - 12 + 8x + 2 = 180
19x - 10 = 180
19x = 190
    x = 10

m<AEB= 11x - 12 = 11(10) - 12 = 98
m<CED = 4x+1 = 4(10) + 1 = 41
m<BEC = m<CED  = 41
so 
m<AEC = m<AEB + m<BEC
m<AEC = 98 + 41
m<AEC =139

answer
m<AEC =139

A cylinder has a volume of 175 cubic units and a height of 7 units. The diameter of the cylinder is
VashaNatasha [74]
The answer is <span>10 units
</span>
The diameter of the cylinder (d) is the twice of its radius (r): d = 2r

The volume (V) of the cylinder with radius r and height h is:
V = π r² h

We have:
d = 2r
r = ?
h = 7
π = 3.14
V = 175π

175π = π * r² * 7
175 = r² * 7
r² = 175/7
r² = 25
r = √25
r = 5


d = 2r
d = 2 * 5
d = 10

If p, q are zeroes of polynomial f(x) =2x^2-7x+3,find the value of p^2+q^2​
Elza [17]

Answer:

p^2 + q^2 = 22/9.

Step-by-step explanation:

For a quadratic function ax^2 + bx + c if the zeroes are A and B then

A + B = -b/a and AB =  c/a.

2x^2 - 7x + 3

Now p and q are the zeroes of the above function so

p + q =  7/3 and pq = 3/2.

Now p^2 + q^2 = (p + q)^2 - 2pq

= (7/3)^2 - 2* 3/2

=  49/9 - 3

= 49/4 -  27/9

= 22/9.
