Hey there! I’m happy to help!
We see that the two equal sides are longer than the base. This means that our a will be larger than b. The problem says that one of the longer sides is 6.3. Since the two longer sides are equal, that means that both longer sides are 6.3 cm. Therefore, we can simply subtract these two from the perimeter to find the shorter side, which is the base.
15.7-6.3-6.3=3.1
Therefore, the length of the base is 3.1 cm.
I hope that this helps!
Answer:
124
Step-by-step explanation:
The prallelogram whose adjacent sides are equal and one vertex angle is 90 degrees is a square.
The value of angle 1 is 90 degrees as the diagonal of the square intersect at 90 degrees.

The value of y is 23.
The diagonal of the square bisect the vertex angle hence the angle of 3x is 45 degrees.

Thus, the value of x is 15 degrees.
The value of 12z is 45 degrees.

Thus, the required value of z is 3.75 degrees.
Answer:
4 pieces with 3 sides
2 pieces with only the top
Step-by-step explanation:
First we need to determine how many squares
9/3 = 3
12 /3 = 4
3*4 = 12
There will be 12 pieces of cake
There are 4 corners
They will have frosting on the top and two sides for 3 total sides
There will be 2 pieces will be in the middle with only the top frosted
