Trigonometry, help If the area of triangle ABC is 21 square units, find sinA if b = 14 and c = 9.

An isosceles triangular banner is displayed at the entrance to a Mathematics Conference. The equal sides of the banner measure 18 feet and the area of the banner is 68 square feet. Find the measures of the three angles of the triangle to the ​nearest tenth of a degree​.

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.

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

no

explanation:

you can be freinds, and people but not follow people.
