Can you guys help me to find the measure of each angle tysm.

Answers

Answer:

∠EBF = 51°

∠DBE = 17°

∠ABF = 141°

∠EBA = 90°

∠DBC = 107°

∠DBF = 68°

Step-by-step explanation:

Hope this helps

Answer:

a. m<EBF = 90 - 39 = 51

b. m<EBA = 90

c. m<DBE = 90 - 73 = 17

d. m<DBC = 90 + 17 = 107

e. m<ABF = 90 + 51 = 141

f. m<DBF = 17 + 51 = 68

<ABD, <DBE, <EBF, <FBC, <DBF

<ABF, <DBC

<ABE, <EBC

Factor x3 ‒ 11x2 ‒ 7x + 77 by grouping. What is the resulting expression?a

(x2 ‒ 7)(x ‒ 11)

b

(x2 ‒ 7)(x + 11)

c

(x2 ‒ 11)(x + 7)

d

(x2 ‒ 11)(x ‒ 7)

Answers

Answer:

A. $(x^(2)-7)\cdot (x-11)$

Step-by-step explanation:

The third order polynomial is factored herein:

$x^(2)\cdot (x-11) - 7\cdot (x-11)$

$(x^(2)-7)\cdot (x-11)$

Which represents answer A.

T he equation for a parabola with directrix y = –p and focus (0, p) is:1.What is the parabola’s line of symmetry?

y-axis
x-axis
x = p
x = -p

Answers

The equation for a parabola with directrix y = –p and focus (0, p)

The distance between vertex and directrix is P

Also the distance between vertex and focus is also P

Focus (0,p) so focus lies on y axis

Directrix line is paralled to focus point

So Directex crosses the x axis .

Hence line of symmetry lies is the y-axis.

The graph is attached below.
