Answer:
7 is a obtuse and 2 is acute
Answer:
A) 147.6 sq m
Step-by-step explanation:
Separate the pyramided out into 4 triangles and add those
3 of them (sides) will be the same

This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.
The area of all 3 sides together is 40*3 = 120 sq m
For your base, your height will be 6.9 and your base is 4
A = 13.8 sq m
multiply by 2 again for the entire base
A=27.6 sq m
Now add both
120 + 27.6
Hi,
so you have two triangles of the same side on two sides of the shape.
The shape is the same size split in half.
So 5cm is added twice
then you consider the other time so that’s twice again.
Then you do the same with 15
so it should be
15
5 5
4.6 4 15 4 4.6
5. 5
15
then you just solve for the area
Answer:
The estimate is about 47
Step-by-step explanation:
45.67 ~ 45.5
1.42 ~ 1.5
1.5 + 45.5 = 47
