Answer:
74°,74° and 106°
Step-by-step explanation:
180 -106=74°
The two opposite interior angles=74°each
The other one=106°
20 is the area
And 18 is the perimeter
Qiestion:
Select all that are true.
A. 6.22 - 4 = 6.28
B. 14 - 0.02 = 0.12
C. 3.31 - 2.25 = 1.06
D. 5.48 - 4.96 = 0.52
E. 41.5 - 33.25 = 29.10
Answer:
C and D are the answer
Answer:
56
Step-by-step explanation:
The angle sum theorem *I think* is that for an n-sided shape, the total sum of its angles is 180(n-2).
The sum of a triangles' angles is 180 degrees.
Therefore 4v-44 = 180.
v - 11 = 45
v = 56 degrees
Note: always check if the answer makes sense
