Answer:
41°
Step-by-step explanation:
the sum of the interior angles is 180 degree
so,
38 + x + 101 = 180
139 +x = 180
x = 180 - 139
x= 41°
Answer:
its positive.
Step-by-step explanation:
X + x + x + x + 2 + 2 = 24 Length: (x + 2) = 5 + 2 = 7 inches
4x + 4 = 24 Width: (x) = 5 inches
-4 -4
4x = 20
divide by 4 on both sides
x = 5
Formula for area of a triangle is 1/2 x base x height.
musing the information given you have:
360 = 1/2 x base x 18
First multiply both sides by 2:
720 = base x 18
Now divide both sides by 18:
Base = 720/18
Base = 40 cm
