Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. a coat hanger is in the shape of isosceles triangle abc shown in the figure. sides ab and bc are congruent. if m< bac=22, then m< abc= ?

m∠ABC=136°

Step-by-step explanation:

In the given figure we have a coat hanger is in the shape of isosceles triangle ABC.

Sides AB and BC are congruent.

The isosceles theorem says that the angles opposite to the equal sides of a triangle are equal.

Therefore, in ΔABC, we have

m∠BAC=m∠BCA

If m∠BAC=22°, then m∠BCA= 22°

By angle sum property , we have

m∠BAC+m∠BCA+m∠ABC=180°

⇒22°+22°+m∠ABC=180°

⇒m∠ABC+44°=180°

⇒m∠ABC=180°-44°=136°

⇒m∠ABC=136°

Therefore, If m∠BAC=22°, then m∠ABC=136°

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
