Answer:
36
Step-by-step explanation:
equilateral triangle has all sides So,
perimeter = a+b+c= 12+12+12=36
the length of the bottom side is 17-3 = 10
to be a square all sides need to be 10 units.
A(7,13)
B (17,13)
Answer:
The range of this set of numbers is 9
Step-by-step explanation:
The range is the greatest number subtracted by the lowest number
in this problem that is 21-12
Are you thinking of hundreds? If so, then it would be 307700.
Answer:
D. m∠A=43, m∠B=55, a=20
Step-by-step explanation:
Given:
∆ABC,
m<C = 82°
AB = c = 29
AC = b = 24
Required:
m<A, m<C, and a (BC)
SOLUTION:
Find m<B using the law of sines:
m<B = 55°
Find m<A:
m<A = 180 - (82 + 55) => sum of angles in a triangle.
= 180 - 137
m<A = 43°
Find a using the law of sines:
Cross multiply
