Answer:
115 degrees
Step-by-step explanation:
first find the missing angle in the triangle
75+40+x=180
x+115=180
x=65
That angle plus the ? angle form a straight line, meaning they add up to 180 degrees.
so 65+x=180
x=115
Answer:
$5
Step-by-step explanation:
15x18=270
1170-270=900
900/18=50
I=PRT
r=rate in percent
t=time in years
p=principal
convert percent to decimal
assuming you means at 7%
percent means parst out of 100
7%=7/100=0.07
so ow we have
p=8000
r=0.07
t=5
i=8000 times 0.07 times 5
I=40000 0.07
I=2800
interest=$2800
3x + 4(3x+17) = 8
3x + 12x + 68 = 8
15x = - 60
x = - 4
i am a mathematics teacher. if anything to ask please pm me
This is a same side interior angle, which means that the two angles, when added, will equal 180°
y + 72 = 180
Isolate the y, subtract 72 from both sides
y + 72 (-72) = 180 (-72)
y = 180 - 72
y = 108
A) 108°, is your answer
hope this helps
