Step 2, 5*155= 775,which means the steps after that would make the answer even more variable
Horizontal means the equation is y=something
(x,y)
(0,-2)
y=-2 is the equaiton
or
f(x)=-2
Since the angles are bisecting < RSU = < UST
substitution----- 4x+16=9x-9
subtract 4x from both sides----- 16=5x-9
add 9 to both sides-----25=5x
divide by 5 on both sides------ 5=x
The value of x is 5
substitute the value of x in both expressions
1st expression: 4x+16
substitute the value of x------ 4(5)+16= 20+16=36
2nd expression: 9x-9
substitute the value of x-----9(5)-9=45-9=36
< RST= <RSU+<UST
<RSU=36 degrees
<UST= 36 degrees
------------------------------------you have calculated both above-------------------------------------------
m<RST= 36 + 36=72 degrees
Answer:
0.98001931 is your answer : >
The slope is 3/4. you need to find the change of y over the change of x.
