Answer:The perimeter = 18.6 , The area= 16.56
Step-by-step explanation: The perimeter is all sides added together and there are four sides and two sides are even , so there are two ways to find it. {1} 6.9x2=13.8 , 2.4x2=4.8; 13.8+4.8=18.6…{2} 6.9+6.9+2.4+2.4=18.6.
The area is two sides multiplied together so, 6.9x2.4=16.56
Answer:
122.4 or 122
Step-by-step explanation:
I'm not for sure but I think 43 sorry if I get it wrong
Because both sides are given as 10, the two bottom inside angles would be the same.
Since one of the bottom angles is given as 74 degrees, the other bottom angle is also 74 degrees.
The total of those two angles is : 74 +74 = 148 degrees.
The total of the 3 inside angles of a triangle is 180 degrees.
The top angle (B) is 180 - 148 = 32 degrees.
The answer is B.
