In right triangle ABC, angleC is a right angle and sin A = sin B. What is m angle A?

A. 30
B. 45°
C. 60°
D. 75°

A=45°

Step-by-step explanation:

soln:

given,

ABC is a right angled triangle where C is right angle

i.e. C=90°

sin A= sin B=x(let)

A=?

we know,

A+B+C=180°[°•°sum of angles of a triangle]

or, x+x+90°=180°

or,2x=90°

•°•x=45°

hence,A=45°

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: 30

step-by-step explanation: its 30 because im a basketball player and stephen curry hits most of his shots so if you put 30 you might make the shot goodluck
