Answer:
x = 44 degrees.
Step-by-step explanation:
Hi!
Since m<2 and m<3 equal 180 degrees (sum of flat line), we can form an equation
(x+4) + (3x) = 180
x + 4 + 3x = 180
4x + 4 = 180
4x = 176
Divide by 4 on both sides
x = 44 degrees
Let me know if you have any questions
Answer: Sabrina read 65 pages on the second and third days
Step-by-step explanation:
45 + 2x = 175
45 - 45 + 2x = 175 -45
2x = 130
2x/2 = 130/2
x = 65
CHECK: 45 + 65 +65 = 175
Answer:
see explanation
Step-by-step explanation:
The perimeter is the sum of the 3 sides, that is
perimeter = 8 + 12 + 17 = 37 cm
To use Heron's formula for area (A)
A = 
where a, b and c are the lengths of sides and s the semi perimeter
s = 37 ÷ 2 = 18.5
let a = 8, b = 12 and c = 17, then
A = 
= 
= 
≈ 43.52 cm² ( to 2 dec. places )
Answer:
the answer is -1. please thank my answer please and thank you
Infinite solutions ig without one or more actual number or variable there is no way to get one solid answer. (Im not positive ik im probably very wrong but this is just my guess by looking at it Im barely passing math as is)
