Answer:

92°

Step-by-step explanation:

∠C=180-140=40

∠A+∠B+∠C=180

40+2X+X+2=180

X=46

∠B=46*2=92°

The penny size of a nail indicates the length of the nail. The penny size

Alecsey [184]

In this question ,it is given that

The penny size of a nail indicates the length of the nail. The penny size

d is given by the literal equation

$d=4n-2$

where n is the length (in inches) of the nail.

In the first part we have to solve for n .

And for that firt we add 2 to both sides

$d+2 =4n$

Now we divide both sides by 4, that is

$n = \frac{d+2}{4}$

Part b.

When d=3

$n= \frac{3+2}{4} = \frac{5}{4} = 1.25$

When d =6, we will get

$n=\frac{6+2}{4}=2$

When d =10, we will get

$n = \frac{10+2}{4}= 3$

Geometry - Triangle d) In the given figure, BE = EC and CE is the bisector of ZACB. Prove that ZBEC = ZACD. E B D С

Llana [10]

Answer:

Let m∠BCE = x

Then m∠ACE = x as well since CE is bisecting ∠ACB.

m∠ACD + x + x = 180° ⇒
m∠ACD = 180° - 2x

Consider ΔBEC

Since BE = EC, the opposite angles are congruent:

∠BCE ≅ ∠CBE

Then:

m∠CBE = m∠BCE = x

Find the angle BEC:

m∠BEC = 180° - (x + x) = 180° - 2x

Comparing the above we see that:

m∠BEC = m∠ACD
