Answer:
Angle C = 45 degrees
Step-by-step explanation:
All interior angles of a triangle add up to 180 degrees.
180-72-63 = angle C
Angle C = 45 degrees
It is 3.125 as a decimal :)
Answer:
y = - 2
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
Where c is the value of the y- coordinates the line passes through
The line passes through (2, - 2) and (0, - 2) both with y- coordinate of - 2, thus
Equation of line is y = - 2
(4+x)+x=22
= 4+2x=22
= 2x = 18
= x = 9.

Answer: w ≤ 14 cm , L ≤ 42 cm
<u>Step-by-step explanation:</u>
width (w): w
Length(L): 3w
Perimeter (P) = 2w + 2L
P ≤ 112
2w + 2L ≤ 112
2(w) + 2(3w) ≤ 112
2w + 6w ≤ 112
8w ≤ 112
w ≤ 14
