Answer:
m < B = 22 degrees.
Step-by-step explanation:
There are 180 degrees in a triangle so we have the equation:
x + 120 + x + 16 = 180
2x = 180 - 120 - 16 = 44
2x = 44
x = 22
m < B = 22 degrees.
Answer:
80 inches
Step-by-step explanation:
a²+b²=c²
60²+b²=100²
3,600+b²=10,000
b²= 6,400
b=80
Answer:
19 for each one
Step-by-step explanation:
Divide 57 by 3
Answer:
see explanation
Step-by-step explanation:
using the cofunction identity
sin x = cos(90 - x), hence
sin75° = cos(90 - 75)° = cos15°
Answer:
Let C be the cost price of the article. Then:
C(1+30%)=marked price
So:
C(1+30%)=C(1.3)
=1.3C
If the article is then marked down 35%, then its’ price would be:
1.3C(1–35%)=1.3C(.65)
=0.845 or 84.5% of its’ cost
Then:
0.845–1=-0.155
or, a 15.5% loss on the item
