Answer:

option 3.75°

Step-by-step explanation:

we know that

If two triangles are similar, then the corresponding angles are congruent

so

In this problem

The corresponding angles are

m∠A and m∠D, m∠B and m∠E, m∠C and m∠F

so

m∠A=m∠D

m∠B=m∠E

m∠C=m∠F

therefore

m∠F=75°

Find all zeros.
Jet001 [13]

Answer:

{ 0, 3, - 3 }

Step-by-step explanation:

f(x) = x(2x - 3)(x + 3)

to find the zeros let f(x) = 0 , that is

x(2x - 3)(x + 3) = 0

equate each factor to zero and solve for x

x = 0

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = \frac{3}{2}

x + 3 = 0 ⇒ x = - 3

zeros are { 0, \frac{3}{2} , - 3 }
