Two of the angles in a triangle measure 13° and 5°. What is the measure of the third angle?

162

Step-by-step explanation:

The total amount of degrees a triangle can have is 180.  This means that

13 + 5 + x = 180

Solve for x.

13 + 5 + x = 180

18 + x = 180

(18 + x) - 18 = 180 - 18

x = 162

The angle's measure will be 162 degrees.

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.
